Project Summary:
The purpose of this project is to reconstruct the Interstate 90 eastbound lanes from west of exit 37 (Pleasant Valley Road) to the railroad multi-plate 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), 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.
Project Timeline:
Spring 2022 - June 2024
Project Updates:
April 3, 2024: On Wednesday, April 3, 2024, the remaining work on the project that reconstructed the exit 37 interchange on Interstate 90, near Sturgis, will begin. The remaining work includes pavement repairs in the eastbound lanes, concrete repairs on the westbound on and off-ramps at exit 37, concrete repairs on Pleasant Valley Road, median crossover construction for a future project that will reconstruct exit 34, smoothness grinding of the concrete pavement, pavement markings, storm sewer pipe cleaning, permanent signing, miscellaneous grading and seeding throughout the project limits, and overall project cleanup.
There will be a 16-foot width restriction in place and traffic will be limited to a single lane in each direction, with speed limits reduced to 65 mph through the work zone, and 45 mph when workers are present.
