Chubbuck Road is open for traffic under Interstate 15. As part of the redesign of the System Interchange project Chubbuck Road was rebuilt as an underpass with lanes for bicycles and sidewalks. Over the last month the new underpass was closed so crews could build the eastbound lane, construct sidewalks, paint permanent lines and add signs.
ITD expects no further closures of Chubbuck Road. However, crews will continue to work around the site adding vegetation and doing cleanup work. Drivers are encouraged to slow down for workers on and near the roadway.
No cleanup work will occur during the holiday.
Originally built in the 1960s, the I-86 and I-15 System Interchange is undergoing a rebuild to improve safety and replace aging infrastructure. This week crews are painting the final lane lines throughout the project area. Once the lines are completed the remainder of the project will consist of seeding vegetation and other cleanup work that will not affect traffic.
Motorists are encouraged to use 511.idaho.gov or the 511 app to keep track of project detours. Project details are available on ITD’s projects website at itdprojects.idaho.gov/i-86i-15-system-interchange.
Beginning Monday the Idaho Transportation Department will close Chubbuck Road underneath Interstate 15 to add facilities for bicyclists and pedestrians. The underpass was partially completed and opened for the school year, but with schools out for the summer the contractor will be returning to complete work.
Construction is scheduled to be completed by the end of the month. Traffic will be detoured through the Northgate Interchange while work continues.
The old Chubbuck Road Overpass, built in 1962, made it difficult for large loads travelling north and south on I-15 due to its limited height. As part of the System Interchange project, the department decided to transform Chubbuck Road into an underpass to eliminate height restrictions. The new design includes additional facilities for pedestrians and cyclists. Those changes necessitated a closure for demolition in 2022 and the construction of the two newly completed bridges to carry I-15 over Chubbuck Road.
Originally built in the 1960s, the Interstate 86 and I-15 System Interchange is undergoing a rebuild to improve safety and replace aging infrastructure. Work began in 2022 and is scheduled to be completed this year.
Motorists should carefully follow signs and posted speed limits while traveling through the construction area. With crews working day and night at the System Interchange it is especially important that drivers be alert and travel safely.
Motorists are encouraged to use 511.idaho.gov or the 511 app to keep track of project detours. Project details are available on ITD’s projects website at itdprojects.idaho.gov/i-86i-15-system-interchange.
