Construction Status - April 2014

Both Westbound and Eastbound I-90 traffic has been re-routed through the work zone and have reduced speeds of 35 mph in-place. Interstate detours will continue to be in-place throughout the Spring and Summer months as crews begin construction of the new interstate bridges.

Detours on I-90 are single lane in each direction and commuters should expect delays of up to 15 minutes between the times of 7:30 and 9:00 am for East bound and between the times of 4:30 and 6:00 PM West Bound.

Weather dependent, Alaska Frontage Road between Rock Road and Cameron Bridge Road will be closed starting Wednesday, April 16th. Detours will be in-place. Local business access will be maintained as well as residential access along Alaska Road. This detour is anticipated to last two months and will allow crews to finish constructing Alaska Road South and Frank Road.

Construction continues on the new railroad bridge and the resulting underpass. Crews will continue pouring concrete for the bridge abutments and piers. Completion is anticipated around the end of Spring.

Motorists are reminded to watch for work crews and equipment, as well as signs indicating reduced speed limits and detours. Posted limits are enforced until signs indicate that the work zone has ended. Fines double in work zones.

Weekly project updates will appear in the Bozeman Daily Chronicle, Belgrade News and local radio stations. For the latest construction and weather reports, please dial 511 or visit Local residents and businesses may call 406-388-6832 if they have questions or comments regarding the project.
