The Estrella Drive interchange will have an innovative modern roundabout design that minimizes its footprint while moving traffic efficiently and safely. Based on projected traffic volumes and the freeway's alignment through the area, ADOT determined roundabouts to be a better option than a conventional diamond interchange for this location.
In order to build the Estrella
Drive traffic interchange, construction crews will complete the following work:
- Build 100-foot-long
freeway bridge over Estrella Drive
- Construct two
roundabouts to improve access to the freeway
- Install underground
utilities and drainage structures
- Place foundations for
traffic signals and lighting
During the closure, local traffic
will be detoured to Elliot Road between 51st Avenue and Barehand Road/67th
Avenue.
Crews already have relocated
utilities and constructed bridge columns that will support the bridge.
The
South Mountain Freeway, which is slated to open late 2019, will provide a
long-planned direct link between the East Valley and West Valley and a much-needed
alternative to I-10 through downtown Phoenix. Approved by Maricopa County
voters in 1985 and again in 2004 as part of a comprehensive regional
transportation plan, the South Mountain Freeway will complete the Loop 202 and
Loop 101 freeway system in the Valley.
