145th (SR 202) Crossing Three Concepts: Above Grade- Bridge Below Grade- Tunnel At Grade- Crosswalk with signal tq King County P,IBBS Your BigBackyanl
Separate Grade Crossings - Separate-grade Route - - At-grade Route
Above Grade
Above Grade PRO Separation of movements Vehicle operations not affected Opportunity for Gateway CON Not convenient for local pedestrians High vandalism opp o rt unities Obstruction of existing views
Below Grade
Below Grade PRO Separation of movements Vehicle operations not affected Minimum visual impact CON Not convenient for local pedestrians High vandalism opportunities Drainage Environmental impacts
At Grade
At Grade PRO Provides for local and regional needs Short travel distance/good connectivity Reduces ''Jay walking'' CON Interrupts vehicle traffic movement Users crossing need to wait to cross Does not separate traffic Low visual impact
T ---- Safety Nuances All 3 options are safe if everyone follows the rules. For bridge and tunnel, concerns that local users will choose to jaywalk, rather than walk up or down. Mobility impaired users face 2 bad choices For at-grade crossing, concerns that drivers will not comply with signal (risky or distracted driving) ti King County Your Big Backyard
