Halfway through the second and final construction season, a Nevada Department of Transportation project to repave and enhance Interstate 80 in the Carlin Tunnels area has made great progress.
The project began in May 2013, completely renovating the eastbound Carlin Tunnel and surrounding interstate during the first summer. Now approximately halfway through the project's second construction season, the following major work items have been completed this summer:
· Repaving in westbound tunnel
· Repainting of westbound tunnel and eastbound bridge steel girders
· Bridge deck demolition, installation of one of two new concrete bridge decks and seismic upgrade of four westbound interstate bridges
· Removal of previous westbound tunnel lighting to prepare for installation of innovative LED tunnel lighting system
"Work has been going well, and the project is currently on track to complete in September," NDOT Assistant District Engineer Michael Murphy said. "Drivers will see the same improvements through the westbound tunnel that were made last year to the eastbound interstate. Ultimately, it will be a smoother, safer drive."
In total, the approximately $31 million project by Q&D Construction will improve nearly
three miles of I-80 through the Carlin Canyon. The roadbed leading up to and through the Carlin
Tunnels will be reconstructed, including enhanced roadway drainage and new concrete near
tunnel entrances. Tunnel lighting will be renovated with an innovative LED tunnel lighting
system to improve driver visibility by gradually dimming or brightening lighting to match
outside conditions, the first such system to be used in a roadway tunnel in North America. The
project will also enhance and retrofit eight bridges and improve intelligent transportation systems
such as tunnel monitoring cameras and ice warning system.
Through the remainder of the project, westbound traffic will continue to be detoured to the adjacent old highway U.S. 40, bypassing the under-construction tunnel area. Meanwhile, eastbound traffic will travel through the tunnel in which construction is not underway. Motorists traveling westbound I-80 will see several traffic control changes in the month of August as paving and painting items are completed. Drivers are asked to obey traffic controls and drive at posted construction speed limits, or slower as necessary for conditions.
