LAS VEGAS, NV (KXNT) - Drivers will have something new to assist them along their commute starting Wednesday morning.

Beginning at 10am, 42 Active Traffic Management signs along I-15 between Russell Road and Washington, and along U.S. 95 between Las Vegas Boulevard and Valley View will become activated. The signs are part of Project NEON, the biggest road construction project ever undertaken in the state of Nevada

The full-color LED signs will provide next-generation, real-time driver information about crashes, speed limit changes, and lane restrictions, thereby improving safety and traffic flows by reducing differential travel speeds and the likelihood of secondary crashes for enhanced operational efficiency.

In addition to the already posted enforceable speed limits on the right side and High Occupancy Vehicles (HOV) signage on the left, motorists will notice new sign configurations that include lane control arrows and X’s over the travel lanes.

What Motorists Need to Know

Variable speed limits (located on the right side of the sign structure) override the typical speed limit and are enforceable.

               - Why? If needed, the speed limit can be reduced or increased for improved traffic flow through congested areas. These altered speed limits are enforceable.

HOV signs (located to the left) can be changed and opened to general traffic when at least two lanes of traffic are closed.

               - Why? It helps traffic flow around a crash or work zone. In this scenario, “Open to All” will be posted on the HOV sign on the left, thereby temporarily allowing access to all vehicles, even with one occupant, to legally cross the double white line to use the HOV lane.

Lane control arrows and X’s (located across the top of the sign structure above each lane)

                 Why? Lane control signs will be activated based upon roadway conditions, traffic demand and planned or unplanned activities; otherwise, they will remain dark.

Four different icons will be used to assist with lane control as described below:

                 If motorists need to proceed with caution, the yellow X with the word “Caution” will be posted above the lane.

                 If motorists need to prepare to merge due to a lane closing, the yellow X with the word “Merge” will be posted above the lane.

                 If the lane is closed to traffic, the red X and the word “Closed” will be posted above the lane.

                 Once motorists are beyond the activated lane controls and the lanes are re-opened to motorists, they will see the green arrow with the word “Open” above all lanes.
