CRISIS COALITION Regional Projects Analysis February 2, 215
STUDY BACKGROUND Team of CRISIS Representatives, Parish Presidents and/or their Representatives, Legislators, and MPO Staff shortlisted 19 regional projects for analysis Consideration was given to all regional projects in the State Long Range Plan 1 project was subsequently eliminated Project D (LA1 - LA 3 Connector EB) LADOTD deemed unfeasible
DATA-DRIVEN METHODOLOGY 18 Major transportation projects analyzed Regional transportation model used for comparative analysis (237) Key Metric Daily reduction in regional Vehicle Hours of Travel (VHT) Best Available Cost estimates done in conjunction with DOTD Ratios of costs and benefits derived for comparison

TOLLING ANALYSIS 8 Projects identified for potential use of tolls to help finance Tolling has 2 affects on our data Public dollars needed for the project is reduced Some amount of traffic is diverted due to additional cost to the driver Tolls seldom pay for 1% of the project cost most feasible toll roads require 4% to 6% of the untolled cost

GENERAL FINDINGS Multiple projects are needed for regional congestion relief Highest benefit projects involve crossing the Mississippi River (New bridge and increased use of old bridge) Best benefit/cost projects involve improving commute to Ascension Parish and one additional lane in both directions of I-1 through Baton Rouge Tolling can be a part of broader funding strategy with project tolling revenue projections ranging from 25% to 6% of project cost
REGIONAL SOLUTION I-1 Widening Through Baton Rouge Cost Range 35 M Ascension Commuter Route (I-1 or Airline) Cost Range: 125 M 18 M New River Crossing South of I-1 Bridge (With LA 3 Widening) Untolled Cost Range: 1,1 M 1,6 M Tolled Cost Range: 83 M 1,33 M Increase Use of US 19 Bridge (BUMP or North Bypass) Untolled Cost Range: 775 M 78 M Tolled Cost Range: 3 M 35 M
