Technology installations, including vehicle detection loops, active traffic management signs, upgraded signals and a wrong-way driver alert system, will be completed during these closures.
The Nevada DOT expects the I-15 Tropicana interchange to fully open on Friday, May 16 with high-occupancy lanes remaining temporarily open to all drivers until paving and striping are completed this summer.
Alternate routes are encouraged when possible.
Sign replacement
A separate project converting Interstate 515 signs to Interstate 11 signs is also schedule for this week and will require overnight closures, NDOT said.
To limit traffic impacts, work zones are being restricted to 5 miles per night.
“The Federal Highway Administration officially designated I-515 between the Henderson Interchange and Kyle Canyon Road as I-11 in November 2023,” NDOT said. “The new signage supports the corridor’s goal of improving north-south travel and boosting the regional economy by easing the flow of goods.”
I-11 is expected to serve as a vital link between Mexico and Canada, according to state transportation officials.
