Map: Loop 303 and Greenway Road

SURPRISE, Ariz. -- It's a headache shared by drivers the world over -- construction. It always seems like it takes forever for projects to be completed. In the meantime, there are delays, closures and detours to contend with.

Crews with the Arizona Department of Transportation put the pedal to the metal last weekend when they built a bypass in just 43 hours. Yes, hours.

The intersection of Loop 303 (Bob Stump Memorial Parkway) and Greenway Road in Surprise was closed at 10 p.m. on Friday, Dec. 9. The intersection was back open to traffic by Sunday evening, a full 12 hours earlier than scheduled.

During those 43 hours, crews re-aligned the intersection of Loop 303 and Greenway Road south and west, and installed a temporary traffic signal, as well as concrete barriers, fencing and a sidewalk.

Bulldozers moved and compacted between 8,000 and 10,000 cubic yards of dirt -- enough to fill a hockey rink -- and layered 6,600 tons of asphalt. Crews finished up by installing the barriers and sidewalk, and spraying 30,000 linear feet of pavement markings.

ADOT captured all of the action in a time-lapse video.

This new bypass will remain in place for the next 10 months as ADOT crews build a new Greenway Road overpass. The bypass is designed to minimize the impact of that construction on traffic.

The new overpass is slated for completion by fall 2012.

Loop 303 is a 39-mile freeway stretching from Interstate 10 in Goodyear to Interstate 17 in Phoenix. It's a two-lane roadway from I-10 to Grand Avenue/U.S. 60. There it becomes a four-lane divided highway, terminating at I-17.
