  1. Supplemental Environmental Impact Statement St. Louis Truck Lane Corridor Study February 2009

  2. Program History • 2006 MoDOT Completed the I-70 EIS/ROD • 2007 USDOT selected six “Corridors of the Future” interstate routes in response to Nationwide Congestion Concerns

  3. Program History • 2008 MoDOT Completed the I-70 SEIS, including the St. Louis Truck-Only Lane Feasibility Study • January 2009 Ohio, Indiana, Illinois and Missouri signed COF Partnership Agreement • INDOT currently has an RFQ on the street for the COF I-70 Feasibility Study

  4. Corridors of the Future

  5. Corridors of the Future St Louis I-70 Truck Corridor Study

  6. Corridors of the Future • I-70 one of 6 corridors selected & funded • $5 million discretionary grant from FHWA • Limits: Kansas City, Missouri to Ohio/West Virginia Border (800 miles) • $2 million of the $5 million was used to fund MoDOT’s SEIS • $3 million remaining to study the complete I-70 multi-state corridor St Louis I-70 Truck Corridor Study

  7. MoDOT I-70 SEIS • Project Limits: East of Kansas City, Missouri to West of St. Louis • Origin/Destination Study in Kansas City • Route Feasibility Study in St. Louis to be followed by an Origin/Destination Study • Conclusions of the SEIS: FHWA/MoDOT have approved Truck Only Lanes as the Preferred Alternative for I-70.

  8. Goals of the St. Louis I-70 Truck Corridor Study • St. Louis Feasibility Study to provide: • Connectivity Evaluation • Support for MoDOT’s I-70 SEIS • Begin to address issues associated with Truck-Only Lanes crossing the St. Louis Metropolitan area.

  9. St. Louis Truck Lane Corridor Study Tasks • Study Overview • Existing System Conditions • Screening Criteria • Development of Route Alternatives • Screening of Route Alternatives • Conclusions and Recommendations St Louis I-70 Truck Corridor Study St Louis I-70 Truck Corridor Study

  10. Data Collection • Accident & Traffic Data • Roadway Geometrics • Bridge Ratings & Clearance • Truck & Inter-modal Facilities • Environmental Assets • Cultural Resources • Land Use • Planned Transportation Facilities • Design Criteria (I-70 SEIS) St Louis I-70 Truck Corridor Study St Louis I-70 Truck Corridor Study

  11. Initial Truck Only Lanes Routes Considered Initial Range of Corridors: • I-70 • I-270N, I-270N/370 • East-West Split Option (I-70 EB/I-270N WB) • I-64 • 364/Page Avenue • I-270S: I-270S/I-255, I-270S/I-44, I-270S/I-55 • Route on new alignment/new river crossing St Louis I-70 Truck Corridor Study St Louis I-70 Truck Corridor Study

  12. Refining Options • 3 Reasonable Corridors • I-70 across the New Mississippi River Bridge • I-70 to I-270 to I-70 • I-70 to Route 370 to I-270 to I-70 St Louis I-70 Truck Corridor Study St Louis I-70 Truck Corridor Study

  13. Refining Options • 3 Reasonable Corridors (I-70, I-270, & 370) • Limited adverse travel through metro area • Limited through truck traffic in downtown St. Louis and avoids Poplar Street Bridge • Highest truck percentages • Least right of way constraints • Best connectivity to freight generating facilities and intermodal facilities in metro area • Ability to accommodate Long Combination Vehicles (LCV) St Louis I-70 Truck Corridor Study St Louis I-70 Truck Corridor Study

  14. Evaluation Criteria • Environmental • “Red Flags” • Secondary & Cumulative Impacts • Right of Way • Cultural 4(f)/6(f) • Engineering • Economic St Louis I-70 Truck Corridor Study St Louis I-70 Truck Corridor Study

  15. Evaluation Criteria • Environmental • Engineering • Traffic Congestion • Major River Bridge Capacity & Widening • High Crash Location • Route Continuity • Relative Cost • Economic St Louis I-70 Truck Corridor Study St Louis I-70 Truck Corridor Study

  16. Evaluation of Impacts: St Louis I-70 Truck Corridor Study St Louis I-70 Truck Corridor Study

  17. Evaluation of Impacts: St Louis I-70 Truck Corridor Study St Louis I-70 Truck Corridor Study

  18. Next Step: • Finalize MoDOT’s I-70 SEIS • MoDOT to complete the St. Louis Origin/Destination Study • FHWA to conduct a Feasibility Study for the I-70 Corridors of the Future Program St Louis I-70 Truck Corridor Study St Louis I-70 Truck Corridor Study
