NAMPA: I-84 to be closed overnight Friday between Garrity and Franklin interchanges for bridge demolition

NAMPA - The Idaho Transportation Department will detour Interstate 84 traffic overnight Friday (May 14) for the demolition of the 11th Avenue Bridge over I-84 in Nampa.

The closure will take place between 10 p.m. Friday and 7 a.m. Saturday (May 15).

All I-84 lanes will be closed between the Garrity Boulevard and Franklin Boulevard interchanges. Flaggers will direct interstate traffic via the following detours. Click here for detour map:

For westbound motorists: exit the interstate at Garrity Interchange, travel south on Garrity Boulevard, to the Franklin/Garrity/11th Avenue intersection, then north on Franklin to the interchange to re-enter the interstate.

For eastbound motorists: exit the interstate at the Franklin Interchange and use the same detour route in the opposite direction.

Nighttime lane restrictions also will be in place Saturday through Tuesday (May 15-18) as crews focus on construction preparation and equipment mobilization, shoulder work, guardrail installation, and freeway striping. One east- and westbound lane will be closed between 10 p.m. and 5 a.m. Saturday through Monday. On Tuesday night, the eastbound left lane will be closed but all westbound lanes will remain open.

Reconstruction of the bridge is required to accommodate future lanes on I-84. Beginning later this spring, a project will add one lane in each direction on I-84 between Franklin and Garrity.

McAlvain Construction, of Boise, is the contractor on this $4.1 million project.

ITD and the Idaho State Police caution motorists to slow down and pay attention when driving in work zones, where increased speeding fines and other penalties apply. Motorists are encouraged to plan ahead and dial 5-1-1 or visit 511.idaho.gov for information on the state highway or interstate system.
