Beginning July 11, traffic on Interstate 15 will be shifted to the center lanes of a new bridge over the Virgin River between Brigham Road (exit 4) and Dixie Drive (exit 5) while workers dismantle and reconstruct remaining portions of the old bridge and outside lanes. The I-15 southbound entrance ramp at Bluff Street will be closed.
Drivers intending to travel southbound on I-15 from the Bluff Street interchange will be detoured to 270 E and can then enter southbound I-15 from the Dixie Drive ramp. Construction workers will restripe the Dixie Drive entrance ramp with temporary paint. All entrance ramps for northbound traffic will remain open.
Drivers should anticipate lane restrictions on I-15 the evenings of July 9, 10, and 11 while construction crews set up the new traffic pattern.
Currently, three southbound movements of traffic converge over the Virgin River: mainline I-15 traffic, vehicles using the Bluff Street entrance ramp, and motorists using the Dixie Drive entrance ramp. Closing the southbound entrance at Bluff Street will eliminate one of these merges.
The I-15 Milepost 4-5 and Virgin River Bridges project includes widening I-15 between exits 4 and 5 with the construction of one auxiliary lane in each direction.
