A new I-84 interchange is taking shape near Boise. Here are the latest closures
Starting Thursday, Treasure Valley drivers will encounter nighttime closures when heading west on Interstate 84 toward Nampa.
Westbound I-84 is set to close completely between Ten Mile Road and Garrity Boulevard from 10 p.m. to 6 a.m. each night through Monday, Jan 26., according to the Idaho Transportation Department. Traffic will be forced to exit the freeway and detour along Franklin Road, the department said in a news release Tuesday.
Speed limits will also be reduced.
This round of closures comes about a week after ITD closed the interstate eastbound for four days. Both are part of work on a new “flyover” interchange at the coming Idaho 16 extension. Drivers have likely seen crews placing large girders at the interchange, which is west of McDermott Road along the Nampa-Meridian border.
Once the interchange is complete in 2027, traffic will be able to exit I-84 and get onto the new north-south freeway without stopping. ITD officials have likened the interchange to Boise’s Flying Wye, which is where the I-184 Connector peels off of I-84 west of downtown Boise.
Along with the interchange, ITD plans to open the full Idaho 16 corridor in 2027. Traveling along Idaho 16 from the interstate up to Idaho 44, or State Street, is expected to take seven to 10 minutes.
In the meantime, drivers should know this isn’t the end of detours. In the release, ITD noted that this round of closures will end Monday but that “ongoing nighttime lane restrictions in this area will continue through April in both directions.”
“Over the next year, the public can expect to see a full interstate interchange emerge at that location,” Jill Youmans, an ITD spokesperson, told the Idaho Statesman by email.
