West Bozeman Interchange Bridge Project
Update for the week of June 17:
- The I-90 on-ramp for eastbound traffic to Billings will be closed for one day this week for paving work.
- Your patience is appreciated during ongoing ramp construction at the North 7th Avenue and I-90 Interchange. When completed, the project will create two westbound lanes and improve future traffic flow. Access to North 7th Avenue businesses continues to be available throughout construction.
- Minor delays continue to be possible on Bear Canyon road below the Interstate. Traffic on I-90 is not affected.
- Work crews, equipment, flaggers and reduced speed limits should be expected wherever there is road and bridge work. Speed limits are enforced until signs indicate the work zone has ended.
Project Overview
Construction to replace the dual bridges at the West Bozeman Interchange began in March 2013. This important project will address structural vulnerabilities during earthquakes and to improve traffic capacity and function. The West Bozeman Interchange carries North 7th Avenue traffic over Interstate 90 and provides ramp access to eastbound and westbound I90. The existing bridges will be replaced with one new structure that will include four driving lanes, two left hand turn lanes onto the I90 westbound on-ramp, 5 foot shoulders that can accommodate bicycle traffic, and 5 foot sidewalks that are ADA accessible. Additionally, the westbound on-ramp will be widened to accommodate two lanes. Other improvements will include new luminaires, traffic signing and signals.
The interchange bridge construction will be completed in two phases. Phase 1 will consist of removing the northbound structure (east bridge) crossing I90 and accommodating two lanes of North 7th Avenue traffic on the existing southbound structure while half of the new bridge is being built.
Phase 2 will consist of shifting traffic to the new half of the structure which will accommodate three lanes of North 7th Avenue traffic while the existing southbound structure (west bridge) is removed and replaced with the other half of the new structure. To accommodate potential traffic delays on North 7th Avenue, a temporary traffic signal and lane modifications will be established at the Oak Street intersection.
Impact to I90 traffic will consist of crossovers and lane reductions to accommodate construction activities when needed. Information regarding traffic advisories will be posted on this website, in the local newspaper and on local radio stations as well as the Highway Advisory Radio.
Project construction began in March 2013 and will continue into 2014.
