A six-mile stretch of northbound Loop 101 will be closed through Scottsdale this weekend as the area is primed for a carpool lane construction project.
The northbound lanes will be closed between Indian School Road and Shea Boulevard from 9 p.m. today through 5 a.m. Monday.
Northbound traffic will be forced to exit Indian School Road, go north on Hayden Road and east on Shea Boulevard to return to the freeway. The Arizona Department of Transportation recommends exiting earlier or taking westbound Loop 202 to the northbound State Route 51 to avoid the closure.
ADOT will be setting up a construction work zone for the $47.5 million carpool lane project.
A new HOV, or carpool lane, is being added in each direction along a 15-mile segment of Loop 101 from Loop 202 Red Mountain Freeway north to Princess Drive. A new concrete barrier, lighting, traffic monitoring systems and ramp metering will also be added. Construction is expected to be completed by the end of 2008.
Last month, Loop 101 motorists were affected by two weekend closures farther south along Loop 101 that were also used to set up a construction work zone.
The southbound lanes between Shea Boulevard and Indian School Road will be closed during a future weekend, Scottsdale officials say.
Also on Loop 101, the westbound lanes will be narrowed to one lane between Scottsdale Road and 56th Street in northeast Phoenix from 10 p.m. today to 8 a.m. Saturday for new bridge construction. Two lanes will be open in the same area from 8 a.m. to 10 p.m. Saturday, then narrowed to one lane again from 10 p.m. Saturday to 9 a.m. Sunday. ADOT recommends using Frank Lloyd Wright Boulevard and Bell Road as alternate routes.
