Reactor vessel on state roads again Monday

The largest object to travel on Nevada roads will set out on its over weeklong journey this week.

The 1.5 million-pound, 16.5-foot-diameter decommissioned reactor pressure vessel from Southern California Edison’s San Onofre Nuclear Generating Station will hit the road Monday morning from Apex in North Las Vegas, the Nevada Department of Transportation announced Friday.

To keep the load off Interstates 15 and 80, the vessel will mainly travel on U.S. Highway 93 and State Route 318 before crossing the Utah border on its way to Clive.

The massive load will be transported by Emmert International on a 122-foot-long trailer powered by six heavy-duty Class 8 trucks.

Pilot cars and Nevada Highway Patrol vehicles will escort the rig and help with scheduled pullouts and traffic control.

The total convoy will span up to 2 miles in length, including extra trucks, mechanics and project managers.

The massive weight of the super-load will be dispersed across 460 tires, preventing damage to state roads and bridges.

Crews will reinforce drainage culverts along the route using shoring and hydraulic jacks to prevent damage to public infrastructure.

Mobile messaging signs will alert motorists of potential delays and detours.

The load will be traveling at slow speeds during its estimated eightday journey to the Utah border.

Those traveling on U.S. 93 on Monday can expect a 20-mile detour on State Route 168 and should plan for delays.

The load will not be traveling from July 3 through July 5 to minimize impacts to holiday traffic.
