Project Summary
The Missouri Department of Transportation (MoDOT), working with its consultant Jacobs Engineering Group, is preparing for a bridge replacement and interchange improvement project at Route A/B, over Interstate 70 near Pendleton in Warren County.
The purpose of the project is to replace the existing aging bridge structure with a wider bridge, allowing for the addition of shoulders and turn lanes.
The project will include realignment of the bridge and roadway, allowing for most of the construction to be accomplished off-line while maintaining traffic flow on the existing roadway. Periodic closures and detours will be necessary to allow for mainline and tie-in construction work.
Improvements at this location include:
- A corridor realignment with the new bridge to be constructed east of the existing location
- A new 56’ wide bridge consisting of 12’ driving lanes, 12’ left turn lane and 10’ shoulders
- A southbound Route B right turn lane to West Veterans Memorial Parkway
- A northbound Route B right turn lane to eastbound I-70 on-ramp
- Interchange improvements to accommodate the proposed I-70 template with the addition of a third lane, and improved bridge clearance and span lengths
** This project is scheduled to be completed prior to the start of the bridge replacement project on Routes E/Y, over I-70 in Jonesburg in Montgomery County.
