Serving the Big Horn Basin for over 100 years
An all-night inspection of the existing lighting system inside the big tunnel west of Cody on US14/16/20 is scheduled for Thursday, April 20.
Contractor Casper Electric of Casper will limit traffic to a single lane beginning at 7 p.m., April 20, and continuing for 12 hours through 7 a.m., April 21.
“Casper Electric will be measuring and reviewing the existing lighting system to prepare for replacement of the existing lighting system,” said Wyoming Department of Transportation resident engineer Todd Frost of Cody.
One-way traffic will be maintained during the 12-hour closure with flaggers and a pilot vehicle.
“Motorists can expect a 10-minute delay during the all-night lighting inspection,” Frost said.
Casper Electric is the prime contractor on the $5.184 million lighting replacement project inside the big tunnel west of Cody. Casper Electric’s work includes removal and replacement of the existing tunnel lighting system.
“The existing tunnel lighting system is outdated and spare parts are no longer available,” Frost said. “The new system will consist of LED lighting that is more energy efficient. There will also be a tunnel warning system installed to notify motorists of pedestrians and/or bicyclists in the tunnels.”
Project work is tentatively scheduled to begin in May with work at night, 7 p.m. to 7 a.m., 6 days a week, in a 153-calendar-day window. During the 153-day project, motorists should expect a one-lane road with a pilot vehicle and flaggers during working hours with cumulative delays of up to 10 minutes. Traffic will be returned to two-way traffic with no delay during non-working hours.
Project limits for the lighting project begin at milepost 45 (west end of the big tunnel), extending 1 mile east (east end of the short tunnels) toward Cody at milepost 46.
Contract completion date is Oct. 31, 2023.
