AMERICAN FORK — Construction teams on the Utah Department of Transportation's Utah County I-15 Corridor Expansion project are scheduled to close I-15 in both directions at the American Fork 500 East interchange from 11 p.m. Thursday to 5:30 a.m. Friday.

Workers will be pouring concrete on the new north bridge decks. The 500 East bridge is one of 63 structures on the I-15 CORE that will be new, rebuilt or modified within the 24-mile project, according to UDOT.

During the closure, northbound travelers will be diverted from Pleasant Grove Boulevard to 2000 West to State Street and to Main Street in American Fork, to reconnect with I-15. Southbound traffic will be diverted through the on- and off-ramps at 500 east.
