I-80 in Salt Lake City about to shrink to one lane during overnight hours through September

(Francisco Kjolseth | Tribune file photo) Motorcycles travel along I-80 in Salt Lake City, May 13, 2019. Closures and lane restrictions in this and other areas were announced by UDOT.

From now through September, overnight travel on Interstate 80 in Salt Lake City will be slower and trickier.

Every night, both directions of the freeway between State Street and 1300 East will be reduced to one lane between about 9 p.m. and 6 a.m. The Utah Department of Transportation says drivers should plan for delays of 15 minutes or more.

Also, during daylight hours on Saturdays and Sundays, the freeway will be reduced to two lanes in each direction.

Next week, freeway on-ramps from 1300 East to westbound I-80 also will close from Monday at 6:30 p.m. to Tuesday at 6 a.m., and again between Tuesday at 6:30 p.m. until Wednesday at 6 a.m.

The restrictions are for a bridge maintenance project.

UDOT also warns about a few other projects that could impact traffic:

• In Salt Lake City, southbound I-15 will be reduced to four lanes during the day, and to three lanes at night, near 1700 South while crews replace damaged barriers and storm drains from the tanker fire earlier this year. Lane closures will begin Friday at 9 p.m. and all lanes will reopen by Monday at 5 a.m.

• In Saratoga Spring, crews will open a new continuous flow intersection at Redwood Road and Pioneer Crossing on Sunday morning.

Before that, crews will disable all traffic signals at the intersection from Saturday at 10 p.m. until Sunday at 6 a.m. During those hours, Pioneer Crossing will be closed from Crossroad Boulevard to Redwood Road.

A video showing how the new intersection will work is available online at http://udot.utah.gov/redwoodsaratoga.

• In Orem, westbound 800 North will be closed at University Avenue for two nights this weekend, on Saturday and Sunday from 9 p.m. to 6 a.m. Crews will be installing a new storm drain in the area..

Construction schedules are weather-dependent and subject to change. Updated information is available online at udottraffic.utah.gov, or on UDOT’s traffic app.
