DECLO, Idaho (Press Release) – Interstate 84 will be closed to traffic and all vehicles detoured for four nights over the next two weeks for a series of concrete pours on the westbound Snake River bridge at milepost 216 near the Declo Interchange.

Detours of I-84 will begin at about 10 p.m. on Monday (May 2), May 5, May 12 and May 16 and will last about six hours each night. The contractor is using a concrete pumping truck from the eastbound I-84 bridge to transfer the concrete to the driving surface of the westbound bridge.

Concrete placement begins in the middle of the bridge and works toward each end. Additional daytime pours will be accomplished from the east and west end of the structure.

During nighttime closures, all traffic will be detoured between the Heyburn Interchange (Exit 211) and the Declo Interchange (Exit 216). Westbound traffic will be detoured off I-84 at Exit 216, go 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.
