I-84 night closure, traffic switch at Snake River bridge near Declo Monday night (Aug. 1)
DECLO – An overnight closure of Interstate 84 will detour all traffic on two established routes around the Snake River crossing east of Burley Monday night (Aug. 1). When traffic returns to I-84 early Tuesday morning, all traffic will be driving across the new Snake River bridge.
All traffic will be detoured between the Heyburn Interchange (Exit 211) and the Declo Interchange (Exit 216) beginning at about 10 p.m. Monday. During the closure, the contractor for the Snake River bridge replacement project will alter the travel lanes through the construction limits to shift all traffic onto the new westbound bridge. The overnight work is expected to be complete, and traffic returned to I-84, by 6 a.m. Tuesday.
Westbound traffic will be detoured from I-84 at Exit 216, south to Declo on Idaho 77, west to Burley on Idaho 81 and return to I-84 through Heyburn. Eastbound traffic will leave I-84 at Exit 211, detour north on Idaho 24 to Rupert, then east and south on Idaho 25 to I-84.
Following Tuesday’s switch, a 65-mph speed limit will be in effect through the construction zone. A 12-foot width limit will be in effect for westbound traffic and a 15-foot width limit for the eastbound lane.
Ralph L. Wadsworth Construction, of Draper, Utah, is the contractor for the $17.88 million project to replace the two I-84 bridges crossing the Snake River.
Work to replace the westbound bridge started in May 2015, with the installation of a temporary work bridge and removal of the former structure. Construction of the new bridge began in September 2015. Work will begin immediately to dismantle and demolish the eastbound bridge. The new eastbound bridge and all associated work is expected to be complete by mid-summer 2017.
The new bridges will be slightly longer, feature wider shoulders, include fewer piers in the water, and increase vertical clearance for river traffic. The 1,100-foot structures, built in 1960 as part of the original interstate construction, were both considered structurally deficient before being scheduled for replacement. Nearly 15,000 vehicles per day travel on I-84 at this location.
