PROVO — The Utah Department of Transportation is cautioning motorists about two construction projects Sunday and Monday in Provo and Orem.

Construction crews working to repair potholes on I-15 will shut down several lanes on Sunday in Provo's freeway S curve area. Motorists will be restricted to one lane in alternating directions from 7 a.m. to 3 p.m.

Orem's busy 800 North and Courtesy Way intersection will be closed Monday between 7:30 a.m. and 3 p.m. so crews can install a waterline. UDOT is asking that motorists use 400 West or 600 West as an alternate route.

Motorists should use caution, travel more slowly and follow signs and devices in the area, UDOT said.
