According to a press release from the Utah Department of Transportation, the eastbound lanes of I-84 in Weber Canyon will be closed Sunday at 9 a.m. to facilitate bridge construction.

“The closures will allow crews to install bridge beams for two new bridges over the river and railroad tracks just east of the mouth of Weber Canyon,” the release said. “The existing bridges were built in 1965 and have undergone multiple repairs and rehabilitation projects over the past two decades.”

The eastbound lanes of I-84 will shut down at 9:30 a.m. Sunday and reopen on Monday at 4 a.m.

The UDOT release lays out a detour route but notes that drivers with long vehicles will especially have to prepare ahead of time.

“During this closure, eastbound I-84 drivers will be detoured onto northbound I-15, then eastbound SR-39 (12th Street) through Ogden Canyon, until they reach southbound Trappers Loop Road (SR-167) before reconnecting with I-84 near Mountain Green,” the release said. “Because vehicles longer than 50 feet are prohibited in Ogden Canyon, all RVs, trucks pulling trailers and other vehicles exceeding this length will need to take an alternate route. Oversized vehicles should use southbound I-15 to eastbound Interstate 80 and continue through Parleys Canyon to the I-80 and I-84 interchange near Echo.”

The same closure will also occur June 21, 22 and 23 from 2:30-9:30 p.m.
