About seven miles of I-90 will be resurfaced from the Big Creek Exit to the West Wallace Exit.
Based on life-cycle cost analysis and current market prices, existing concrete sections will be replaced with asphalt. Guardrail will also be updated.
In 2023, work will focus on reconstructing I-90 from Osburn to Wallace. This season all traffic will be reduced to one lane in each direction and shifted onto the westbound set of lanes to give crews room to work on the eastbound set of lanes.
At the start of construction the eastbound on- and off-ramps at the Silverton Interchange will close for several months. Drivers trying to access eastbound I-90 will need to use either Exit 57 in Osburn or Exit 61 in Wallace.
Construction in 2024 will include all lanes from the Big Creek Exit to Osburn and the westbound lanes from Osburn to Wallace. Reconstruction of the section between Big Creek and Osburn has been scheduled for 2024 to give drivers a break from work zones on I-90.
