ADOT say 'south half' of large interchange will open in fallPosted: Updated:
As the Arizona Department of Transportation (ADOT) continues its $63 million project to create a traffic interchange that links Loop 303 with Interstate 10 in the west Valley, it predicts the “south half” of the interchange to be completed by late fall in 2017.
Completion of the “south half” will include extending Loop 303 south from Thomas Road to Van Buren Street. The construction has been underway for nearly a year now.
The entire project will include four new freeway-to-freeway ramps, while sections of two elevated ramps will temporary rise above I-10 on temporary construction supports, according to ADOT.
Crews working on the elevated ramps have minimized the need to work over live I-10 traffic through engineering decisions that have created these alternative ramps during construction.
The next steps for the project include the opening of a new southbound Loop 303 frontage road in the spring, which will allow both northbound and southbound traffic to travel through the interchange work zone while construction continues, according to ADOT. Concrete pavement will also be poured along Loop 303 where the future freeway travels beneath 1-10 toward Van Buren Street.
Once completed, the new ramps at the Loop 303 and I-10 interchange will allow direct connections between the freeway and Cotton Lane south of Van Buren Street. Southbound traffic on Loop 303 will no longer be required to exit at Thomas Road, but instead will be able to travel beneath I-10 to Cotton Lane, allowing northbound travelers to transition directly onto Loop 303.
Frontage roads and interim ramps will allow drivers to continue to use Cotton Lane, between McDowell Road and Van Buren Street, during construction.
This multi-million dollar project will also work to diminish the flooding problems that exist along the freeways during storms. ADOT said the project will create storm-water basins and a channel to direct excess runoff southward into a new regional flood control system leading into the Gila River.
