The Nevada Department of Transportation has updated the dates for the upcoming overnight closures of Interstate 15 (I-15) to accommodate the installation of new Active Traffic Management signs. Commuters should now mark their calendars for December 4th and 5th for when the closures will take effect, according to the Nevada Department of Transportation announcement.
On the night of December 4, starting at 9:00 p.m. and expected to extend until 5:00 a.m. the following morning, southbound I-15 will be inaccessible from Flamingo Road to Russell Road. Along with this major closure, several on-ramps and off-ramps will be closed to traffic, including the busy Tropicana Avenue and Harmon Avenue access points. Motorists planning to traverse the area will face reduced lanes, with northbound I-15 narrowing down to three lanes from Hacienda Avenue up to Flamingo Road, as reported by the Nevada Department of Transportation.
The disruption continues into the next night, beginning at 9:00 p.m. on December 5 until the early morning of December 6th, with the closure shifting focus to the northbound lanes from Russell Road to Tropicana Avenue. Impacted will also be the westbound I-215 ramp to northbound I-15, although access to Frank Sinatra Drive and Russell Road will be maintained. Southbound lanes between Flamingo Road and Hacienda Avenue will also see a reduction to three lanes, as per the Nevada Department of Transportation.
The purpose behind these inconvenient closures is the installation of Active Traffic Management signs, designed to deliver real-time information to drivers and help improve the flow of traffic. These signs, described as "heavyweights of technology," are not only impressive in weight—the single-span signs tip the scales at approximately 46,000 pounds—but in their capabilities as well. They have the power to dynamically adjust speed limits or display lane-use instructions, basing these decisions on live traffic conditions. According to the Nevada Department of Transportation, systems like these have reduced secondary crashes "by up to 30%," which is an instrumental factor for the safety of high-traffic areas like Southern Nevada.
For those seeking to avoid the closures and potential delays, Nevada Department of Transportation encourages using caution through work zones and considering alternate routes.
