SALT LAKE CITY — Travelers in Utah should expect significant delays this weekend near downtown Salt Lake City and on one of Utah’s main recreation routes to and from Moab and Lake Powell at Spanish Fork.

US Highway 6

Interstate 15 connects southeastern Utah to popular recreation areas such as Moab and Lake Powell via U.S. 6 at Spanish Fork Canyon. The route passes Soldier Summit and is four lanes in sections, but will be reduced to one lane starting Sunday, Aug. 11, through Aug. 15 for bridge repairs, according to the Utah Department of Transportation.

“Significant delays are expected,” the agency said in a press release. “UDOT encourages vacationers and commuters to use the Spanish designation for Main Street to Canyon Road or State Route 77 to US 89 as alternate routes to avoid major delays.”

The work will last from 6 a.m. to 7 p.m. daily, but lane closures will remain in place the entire time as workers replace the bridge deck. The same lane closures will be repeated August 18-22. US 6 runs east-west through the middle of the state. Also called the Grand Army of the Republic Highway, it also crosses much of the US east-west, running from Bishop, California, to Provincetown, Massachusetts.

City

Salt Lake City’s 500 South, including the ramps to I-15 southbound and Interstate 80 westbound, will be closed from 500 West to the freeway ramps from 11 p.m. Friday to 8 a.m. Saturday. Crews will replace signs on the pavement and work through the night.

In addition, the pavement marking crew will travel “throughout the Salt Lake Valley” to install wider pavement markings for better visibility and reflectivity on both I-15 and Interstate 215. UDOT will close adjacent lanes and on- and off-ramps during this work. Crews will work throughout the night, beginning at 9 p.m.

• On Saturday, August 10, workers will be working on I-80 eastbound in Parleys Canyon near Lambs Canyon
• On Sunday, August 11 and Monday, August 12, crews will work on I-15 northbound from the I-215 northbound interchange to the I-80 eastbound interchange. Temporary ramp closures are expected on I-215 westbound to I-15 northbound, 4500 South and 3300 South eastbound on I-80, and the Spaghetti Bowl ramps.
