2.6 BUILD ALTERNATIVE OPTIONS

Transcription

1 2.6 BUILD ALTERNATIVE OPTIONS As set forth in a 21 June 2001 Resolution of the CTB, with approved amendments by the CTB on 15 July 2004, the Adopted Location Corridor (ALC) proposed alignment, would extend within a corridor that generally parallels I-581 and U.S. Route through Roanoke, Franklin, and Henry counties, Virginia. This mile-long corridor would comprise part of Virginia s link in the planned I-73 addition to the NHS that would extend between Sault Ste. Marie, Michigan and Myrtle Beach, South Carolina. The new limited access highway would be constructed to freeway design standards within the study area and would ultimately connect with other segments of I-73 alignments in West Virginia and North Carolina. In its 21 June 2001 resolution, the CTB resolved that the proposed limited access highway be designated as Virginia Interstate 73. On July 15, 2004, the CTB rescinded and amended the June 21, 2001 action as follows: Amending action approving Segment Alternatives 376, 287A and 399, as Segment Alternatives, to be rescinded Amending action approving Segment Alternatives 118 and 118B, as a connector to U.S. Route 200, to be rescinded. Approval of Segment Alternatives 375, 118, 118B and 118C, and designation of these Segment Alternatives as a Limited Access Highway and add them to the Interstate System of Highways as a part of Virginia I- 73. The Build Alternative would include all improvements in the No-Build Alternative, plus a new interstate with full access control. No turn lanes, cross traffic, or driveway access would be permitted on the new interstate. The Build Alternative would be built to interstate (freeway) design standards with a minimum of four travel lanes (two in each direction) (see Figure 2.6-1A). The I-581 portions of I-73 would have a minimum of six travel lanes to accommodate forecasted increases in traffic. Four primary options were considered as routes or alignments for I-73. Each option uses a combination of segments that are representative of various potential combinations. Each option is described briefly below. Option 1 (see Figure 2.6-3a through 2.6-3d) would be the most eastern alignment, beginning on I-81 in Botetourt County near Exit 150 and continuing south through western Bedford County and northeastern. Option 1 would continue southerly through eastern Franklin and Henry counties. The alignment would rejoin U.S. Route in. Option 2 and its three variations (see Figure 2.6-4a through 2.6-4d) would follow I-581 south then turn easterly south of State Route 24 to cross the Blue Ridge Parkway. At Route 116, Option 2 would continue southerly in a route parallel to and east of U.S. Route. The Option 2 alignment would rejoin the U.S. Route alignment for a short distance in southern. It would then depart from the U.S. Route corridor, north of the Franklin/ line, and extend to the southeast crossing existing U.S. Route 58 east of Laurel Park. This option and its variations would use much of the existing U.S. Route 58 alignment until rejoining U.S. Route south of Martinsville. The Option 2 variations continue south to the North Carolina state line on a new route west of existing U.S. Route. South of Ridgeway in, Option 2 would rejoin the existing U.S. Route. Option 3 (see Figure 2.6-5a through 2.6-5d) would follow the existing alignments of I-581 and U.S. Route and include the of existing U.S. Route to full interstate standards. The three variations of this option would leave the existing U.S. Route alignment in locations where topographic or other constraints present a challenge. These variations use both existing U.S. Route bypasses east of Rocky Mount and west of Martinsville in the alignments. Option 4 (see Figure 2.6-3a through 2.6-3d) would be a western alignment that would begin in western Roanoke County on I-81 at existing Exit 132 (Dixie Caverns interchange). The alignment would extend east and turn to the south near the western edge of the City of Salem, crossing the Blue Ridge Parkway and continuing south into. Option 4 would continue south on the west side of existing U.S. Route through Roanoke and Franklin counties and into. This option would rejoin U.S. Route east of Martinsville, then diverge south of Martinsville before returning to the U.S. Route alignment south of Ridgeway for the remainder of the corridor Final Environmental Impact Statement

18 In most cases, I-73 would be a four-lane divided highway typical section. Exceptions are I-581 and the portion of U.S. Route between Elm Avenue and Route 419. Potential interchanges were assessed at strategic locations along the mainline of each of the build alternatives. Criteria for location selection of interchanges included roadways that had one or more of the following characteristics: Functional classification of the intersecting roadway. Functional classification indicates the significance of the roadway to the locality, the region, the state, and the nation. In general, the higher the functional classification, the more significant contribution the roadway makes to the transportation network. Potential interchanges for all NHS roadways (including I-81, U.S. Route, U.S. Route 460, Route 40, and U.S. Route 58) were included for assessment. Urban and rural arterial designations as well as state primaries were likewise targeted for interchanges. This included Route 24, U.S. Route 221, Route 57, Route 87, and others previously mentioned. Traffic volumes along intersecting roadway. High volume urban and rural roadways were provided interchanges where safety and geometric conditions warranted. This included existing I-581 interchanges at Peters Creek Road, Hershberger Road, Orange Avenue (U.S. Route 460), Elm Avenue (Route 24), Route 419, and others mentioned above. For high volume interchanges, the need to provide access to immediate land uses and linkage to the adjacent transportation network must be balanced against the practical and safety concerns of controlling access adjacent to off and on ramps. To the extent possible, control of local access within 100 feet of urban access and 300 feet of rural access must be maintained to assure safe ramp junction movements. Linkage with other communities, recreational areas, employment areas and economic development areas. To fulfill the purpose and need, interchanges were located to serve and access areas that are currently or forecast to be developed for recreational, employment or economic development. This included interchanges at Routes 697, 641, 619, 605, 890, 108, and 684. Each new interchange location as well as interchange type is tentative at this point and based on preliminary information that is subject to change as the design is refined and the traffic analysis is updated. The following subsections discuss each of the four basic build alternative options and their variations in more detail Build Alternative Options Considered But Not Selected Build Alternative - Option 1 Option 1 (see Figures 2.6-3a through 2.6-3d) would begin at a modified interchange with I-81 at approximately Exit 150, just north of Cloverdale in Botetourt County. It would extend southeast, crossing existing U.S. Route 460, the Blue Ridge Parkway, and the Blue Ridge Mountains near the community of Blue Ridge. Through Bedford County, the alignment would stay east of Greens Knob and Horsepen Mountain, crossing Route 24 west of Stewartsville. It would then turn southwest and enter south of Explore Park and Prater Creek. The route would stay west of Lynville Mountain. From there it would continue south crossing the Route 116 and staying west of Kennett and then continuing south in the vicinity of Red Valley, Burnt Chimney, Redwood, and Patti. It would turn to the southwest around Fork Mountain, then back southeast, running east of Figsboro and Laurel Park. The interstate would remain east of the existing U.S. Route 58 Bypass and Ridgeway before connecting into the existing U.S. Route immediately south of the North Carolina state line. The approximate length of Option 1 would be 79 miles (126 kilometers). Fifteen potential interchange locations would include two in Botetourt County, two in Bedford County, five in, and six in. The proposed locations and conceptual type of interchange are: I-81 near milepost 150 Botetourt County New Directional U.S. Route 460 east of the Blue Ridge Parkway Botetourt County Cloverleaf Route 24 west of Stewartsville Bedford County Diamond 2-50 Final Environmental Impact Statement

An undercrossing at the Blue Ridge Parkway south of Route 640 would be proposed in Botetourt County. Railroad crossings would be generally in bridge structures to meet clearance requirements of the railroads. Major river crossings under this alternative would include the Roanoke River east of Explore Park, the Blackwater River, the Pigg River south of Redwood, and the Smith River east of Eggleston Falls. The proposed alignment of Option 1 would cross between Martinsville Reservoirs One and Two, crossing over tributary creeks Build Alternative - Option 1a Option 1a (see Figures 2.6-3a through 2.6-3d) is similar to Option 1 with some variation on the alignment. From a point just south of Red Valley, this option would depart from Option 1 and extend west near Bonbrook, crossing existing U.S. Route between the western and eastern legs of Route 697 west of Wirtz, before turning south. It would remain west of Rocky Mount, crossing U.S. Route again north of the Franklin/ line. Option 1a would continue southeast to the west of Figsboro, crossing Route 108, and would connect back into Option 1 southwest of Dyers Store east of the Martinsville Reservoir One and west of Reservoir Two. This option would be approximately 78 miles (126 kilometers) in length and, from north to south, would include segments 372, 399, 400, 144, 381, 192A, 321, 387, 329, 373, 333, and 398. Proposed interchanges would include two in Botetourt County, two in Bedford County, five in, and six in Henry County. The proposed locations and conceptual type of interchange would include: I-81 near milepost 150 Botetourt County New Directional U.S. Route 460 east of the Blue Ridge Parkway Botetourt County Cloverleaf Route 24 west of Stewartsville Bedford County Diamond Route 634 south of the Route 619 intersection Bedford County Diamond Route 657 at Red Valley Diamond U.S. Route between the junctions of Route 697 near Diamond Wirtz Route 641 northwest of Gogginsville Diamond Route 40 west of the Pigg River Crossing Diamond U.S. Route at Route 609 Diamond Route 108 south of Figsboro Diamond Route 57 southwest of Dyers Store Road Diamond 2-51 Final Environmental Impact Statement

20 U.S. Route 58 east of the Route 648/Route 620 intersection Cloverleaf Route 650 near the Tanyard Creek Crossing Diamond Route 87 north of the Route 750 intersection Diamond U.S. Route south of intersection with Route 689 Trumpet Major river crossings include the Roanoke River east of Explore Park, Blackwater River west of Gogginsville, the Pigg River at Route 40, and the Smith River east of Eggleston Falls. The crossing of the Blue Ridge Parkway would be the same as in Option 1 in Botetourt County Build Alternative - Option 2 Option 2 (see Figures 2.6-4a through 2.6-4d) would follow I-581 from I-81 to Elm Avenue. The typical section for I-581 is indicated in Figure A new interchange would separate existing U.S. Route from the proposed I-73 in the vicinity of the Belmont neighborhood. This would allow the route to veer east to connect to Route 116 (JAE Valley Road) and generally follow the Route 116 corridor across the Blue Ridge Parkway. North of Windy Gap, I-73 would turn to the southwest and stay below the ridge line of the Blue Ridge Mountains until it turns back to the southeast and crosses the Blue Ridge Mountains in the vicinity of existing Route 657. It would continue southeast to Red Valley and turn south, passing to the east of Hodgesville and Sydnorsville. Option 2 would rejoin the U.S. Route corridor north of the Franklin/ line and would generally follow the same alignment as Option 1a east of Martinsville. After crossing existing U.S. Route 58, however, Option 2 would turn to the west connecting with the existing U.S. Route 58 Bypass, and continuing to a point just west of the interchange at existing U.S. Route Business. At that point, proposed I-73 would parallel U.S. Route to the west of Ridgeway and connect back into existing U.S. Route south of Ridgeway. From north to south, this option includes segments 374, 376, 294, 118B, 400, 153, 202A, 385, 386, 329, 373, 391, 390, 349, 393, and 398. Option 2 would be approximately 78 miles (125 kilometers) in length and would include 20 interchanges. Proposed interchange locations include five of the existing I-581 interchanges in Roanoke County and the City of Roanoke, a new intersection off U.S. Route south of Elm Avenue in Roanoke City, six in, and eight in. The I-581 interchanges at I-81 and Peters Creek Road are being evaluated as part of the I-81 study and are not included in this evaluation. The proposed locations and conceptual type of interchange would include: I-581 at Route 101 (Hershberger Road) Roanoke City Cloverleaf requires I-581 at Valley View Road Roanoke City Flyover requires I-581 at U.S. Route 460 (Orange Avenue) Roanoke City Cloverleaf requires I-581 at Williamson Road Roanoke City Partial Cloverleaf requires I-581 at Elm Avenue Roanoke City Diamond requires U.S. Route south of Elm Avenue Roanoke City Directional Route 657 at Red Valley Diamond Route 697 southwest of Burnt Chimney Diamond Route 40 at Hodgesville Diamond Route 619 northwest of Sontag Diamond U.S. Route /Route 618 Diamond U.S. Route at Route 609 Diamond Route 108 south of Figsboro Diamond Route 57 southwest of Dyers Store Road Diamond U.S. Route 58 east of the Route 648/Route 620 intersection Cloverleaf 2-52 Final Environmental Impact Statement

A new undercrossing of the Blue Ridge Parkway, 1,000 feet (304.8 meters) east of the existing bridge and undercrossing at Route 617 (Pitzer Road) is proposed Build Alternative - Option 2b Option 2b (see Figures 2.6-4a through 2.6-4d) would follow I-581 to Elm Avenue (similar to Option 2) and would continue along existing U.S. Route corridor south of Elm Avenue. U.S. Route would be converted to a limited-access roadway between Elm Avenue and Route 668 (Yellow Mountain Road). Frontage roads would be introduced along portions of the corridor to provide access to existing businesses and residences along this portion of the route. Proposed I-73 would then diverge from the U.S. Route corridor in the vicinity of the Route 668 (Yellow Mountain Road) intersection, extending southeast and connecting to the previously described portions of Option 2 south of the Blue Ridge Mountains in the vicinity of existing Route 657. From north to south, this option would include segments 374, 375, 118C, 118, 118B, 400, 153, 202A, 385, 386, 329, 373, 391, 390, 349, 393, and 398 and would be approximately 77 miles (124 kilometers) in length. Option 2b would include 24 modified or newly proposed interchanges - three in Roanoke County, seven in Roanoke City, six in, and eight in.

A new undercrossing of the Blue Ridge Parkway, 1,000 feet (304.8 meters) east of the existing bridge and undercrossing at Route 617 (Pitzer Road) is proposed Build Alternative - Option 3 Option 3 (see Figures 2.6-5a through 2.6-5d) would the existing U.S. Route to interstate standards. To accommodate existing businesses, frontage roads would be incorporated along portions of the existing roadway. This option would generally follow the I-581 corridor from I-81 to Elm Avenue then continues along U.S. Route for its entire length to North Carolina. The existing access at U.S. Route and the Blue Ridge Parkway may be modified and possibly eliminated. I-73 will cross under the parkway with a wider road section that includes frontage roads (see Figure 2.6-8). The corridor would depart from the present U.S. Route in the vicinity of Route 615 to minimize residential and business relocations. Segments 397 and 380 are proposed to the west of Boones Mill with access to the town via a proposed interchange at U.S. Route in the vicinity of Route 615 and an interchange at Route 739. Option 3 would rejoin the U.S. Route alignment south of Route 919 (Grassy Hill Road) in the vicinity of Route The proposed alignment would continue along the existing U.S. Route corridor and follows the Rocky Mount Bypass alignment and the existing corridor to the line. The alignment would generally follow U.S. Route south of Oak Level, leaving the existing roadway to provide a straighter road to meet interstate standards and to reduce right of way effects. The proposed alignment would continue on U.S. Route through Bassett Forks and would follow the Martinsville Bypass alignment and the corridor south into North Carolina.
