Construction on a 13-mile pavement improvement project along Interstate 15, from just north of Mesquite to the Nevada state line will require crews to close the on- and off-ramps at Exit 8 (Littlefield), Exit 9 (Beaver Dam) from 5 p.m. to 8 a.m. to allow for paving and curing time, according to the Arizona Department of Transportation.

Signs indicating detour routes will be in place while the interchange ramps are closed for paving:
•Feb. 21: Southbound Exit 9
•Feb. 22: Southbound Exit 8, including part of crossroad
•Feb. 23: Northbound Exit 8, including part of crossroad
•Feb. 24: Northbound Exit 9
•Feb. 25: Southbound Exit 9
•Feb. 28: Northbound Exit 9
•March 2: Southbound Exit 9

Motorists should expect brief delays while traveling through the work zone through late spring. In an effort to minimize travel delays, most of the paving work will take place nightly, from 5 p.m. to 8 a.m. Monday through Friday.

The $10.4 million project includes paving a 13-mile stretch of roadway (mileposts 0 to 13), replacing a bridge barrier, sealing the existing bridge deck and installing new guardrail.

Motorists are also reminded to plan for additional travel delays while ADOT continues a major reconstruction of the Virgin River Bridge No. 6 (milepost 16), midway between Mesquite, Nevada, and St. George, Utah. The highway is narrowed to one lane in each direction through the work zone until the project is completed in summer 2016. This $27 million project includes the replacement of the bridge’s superstructure (girders, deck and railings), as well as widening the roadway through the narrow passage of the gorge.

With limited alternate routes through this corridor, drivers should plan ahead, allow extra travel time, slow down and drive carefully through the work zone, and be alert for construction equipment and personnel.
