Nevada transportation officials hope to reopen sometime Friday a section of Interstate 15 between Las Vegas and the Utah border that has been closed since Monday -- however, trucks heading in one direction will continue to have to take a long and painful detour.

The highway has been closed is in both directions, from mile marker 75 to 93, north of Las Vegas between Glendale & Mesquite in Clark County, due to flooding that damaged the roadway.

According to the Nevada Transportation Department, northbound I-15 will continue to be off limits for the next week or more, even once the interstate reopens. This means that commercial vehicles heading from Las Vegas should plan to continue to detour via U.S. 93. The detour is about 250 miles and has been the site of long traffic delays.

Northbound commercial traffic detour: Take I-15, turn onto U.S. 93 northbound and proceed to Panaca, Nevada. At Panaca, turn onto Nevada State Route 319, which turns into Utah State Route 56, and go east to Beryl Junction, where you will turn south onto Utah State Route 18 to St. George.

Until I-15 reopens, the southbound detour remains in place.

Southbound commercial traffic detour: In St. George, Utah, go north on Utah State Route 18 and proceed to Beryl Junction where you will turn west onto Utah State Route 56, which becomes Nevada State Route 319, then proceed west to the town of Panaca where you can turn south onto US93 to I-15 north of Las Vegas.

It is estimated repairs to I-15 will cost around $5 million.
