Car pool lanes on Loop 101 through Scottsdale are a step closer to construction.

The Arizona Department of Transportation has selected a contractor to add the lanes, one in each direction, on a 15-mile stretch of freeway from Princess Drive to the Loop 202 interchange.

Coffman Specialties of San Diego was selected from a field of six bidders, and the State Transportation Board is expected to approve the contract during its July 20 meeting in Payson.

Once the selection is official, work could begin around Labor Day and wrap up in early 2009, ADOT spokesman Doug Nintzel said Friday.

It would be up to the contractor’s discretion to determine when and where the work would take place, although Nintzel said it is anticipated all the lanes would remain open most of the time during construction.

But weekend restrictions are expected. That would be when construction crews would realign the existing lanes away from the median, where the car pool lanes are to be built.

Coffman’s bid came in at $47.5 million, which is $3 million less than ADOT estimated the project would cost.

In addition to the car pool lanes, the contract calls for installing ramp meters, nine overhead message signs and an additional merge lane on the northbound section between Cactus Road and Raintree Drive.

Also, traffic-monitoring cameras will be installed. These cameras are separate from the photo radar speed enforcement system already in place on Loop 101 in Scottsdale.

Construction here is the first step in installing high-occupancy-vehicle lanes along the length of Loop 101 from the Santan Freeway to Princess Drive. The other two phases are from the Loop 202 interchange to Baseline Road, and from there to the Santan Freeway.

The goal, Nintzel said, is to increase traffic capacity while promoting car pools and mass transit between the south East Valley and the commerce center of the Scottsdale Airpark.
