Project Summary:

The purpose of this project is to reconstruct the I90 Eastbound lanes from west of Exit 37 (Pleasant Valley Road) to the railroad multi-plate at MRM 38.34 and the westbound on-ramp and eastbound off-ramp at Exit 40 (Tilford) due to the pavement condition. This will also include replacing the interchange at Exit 37 (Pleasant Valley Road - structure# 47-061-480), PCC surfacing, and replacing all the pipe within the project limits under the EB lanes. Additionally, a new Tilford Port of Entry will be constructed including a new building, new parking lot, and new E-Screening infrastructure.
