NORTH SALT LAKE -- A bump in the road will cause some congestion on Interstate 15 for the next few weeks.
The Utah Department of Transportation is performing extensive repairs to the northbound lanes of I-15 in North Salt Lake, near Mile Marker 313.
Damage was caused in the area about a year ago by the excavation for a gas pipeline under the highway, which eventually caused a dip in the northbound lanes.
Efforts to repair the interstate last year stabilized the road but left a noticeable bump, said UDOT Region One spokesman Vic Saunders.
Crews are now working to repair damage just beneath the surface of the road.
Once the subsurface damage has been repaired and old pavement is removed, a new section of road, less than a mile in length, will be installed.
"We're going to cut out that old section of pavement and lay in a new section that will be totally smooth," Saunders said.
Crews began working on the two outside northbound lanes of I-15 near Mile Marker 313 on Monday night, he said.
Up to two lanes will be closed nightly, from 7 p.m. to 10 a.m. the following day.
During those times, Saunders said, motorists should consider alternate northbound routes, such as U.S. 89, Redwood Road or Interstate 215.
Crews have already completed repairs to a northbound segment of U.S. 89, between Mile Marker 384 and Eagle Ridge Drive, that was also damaged by the pipeline excavation.
With good weather, Saunders said, the I-15 repair work should take three to four weeks.
