Current Phase: Detailed Design
- Detailed Design: Complete June 2020
- Construction (Tentative): Oct/Nov 2020 – Oct/Nov 2021
Gilbert, in partnership with the Arizona Department of Transportation (ADOT) and Federal Highway Administration (FHWA), is in the process of designing a traffic interchange at Lindsay Road and the SR 202 Santan Freeway. This interchange will provide additional access for drivers and ease congestion to Gilbert’s Central Business District, residential areas and the surrounding transportation system.
Gilbert, in partnership with ADOT and FHWA, developed a design concept report (DCR) for the Lindsay Road interchange in 2018, and this DCR was reviewed and approved by the partners.
The Town began design of the interchange in 2018 and has recently completed the design with construction expected to begin in late 2020.

What is a traffic interchange (TI) and what are the benefits?
A traffic interchange is a combination of ramps and grade separations at the junction of two or more highways for the purpose of reducing traffic conflicts, improving safety, and increasing traffic capacity.
Why is a traffic interchange at Lindsay Road needed?
With the Phoenix metropolitan area expanding to the south, the traffic coming from and going to the south is increasing as residents travel to work, shop, learn and play. The lack of an interchange at Lindsay Road has created substantial additional traffic on both Gilbert Road and Val Vista Drive and also restricts development along the Loop 202 near Lindsay. An interchange would provide relief to nearby major arterials and secondary roads, and would enhance access in the area for Gilbert’s residents and businesses and the Southeast Valley as a whole.
What will happen to Zanjero Park if an interchange is constructed?
The access location (driveway into the park) and parking layout is being modified, but there would be no permanent impacts to the park itself. There may be some limitations during construction, but the contractor would coordinate those with the park with the objective of maintaining access.
Will the new interchange construction accommodate pedestrians/trail users?
Impacts to Zanjero Park will be limited to the access point (driveway) and parking area during construction. Construction of the new interchange would include sidewalks and cross walks at the ramp intersections and would provide better connectivity from the transportation system to the park.
If there is an interchange, will Lindsay Road also be widened?
Yes. Capital improvement project ST1170 is currently nearing completion to widen Lindsay Road between SR 202 and Pecos Road to three lanes in each direction. Capital improvement project ST1450 will begin construction soon to widen Lindsay Road between SR 202 and Germann Road, and Germann Road between Gilbert and Val Vista, to three lanes in each direction.
Will adding an interchange change the zoning of the immediately surrounding area?
No. The area surrounding the proposed interchange is already commercially zoned and falls within Gilbert’s Central Business District corridor. It is anticipated the addition of an interchange will support this key employment area.
Is future expansion planned for the Santan Freeway?
Yes, future general purpose and HOV lanes are included in the Maricopa Association of Governments’ program in FY 2022 (HOV lane) and FY 2027-2040 (general purpose lane).
How long will construction take?
The interchange construction is estimated to last 12 months from the start date. Utility relocations may occur before the main interchange construction.
Will there be sound walls as part of the project?
A noise analysis was completed for the project which recommended noise mitigation along the north side of the SR 202L but not along the south side. A portion of the existing noise wall and berm along the north side of SR 202L is being restored per the noise analysis recommendations.
Will there be any additional traffic signals as part of the project, for example at Frye Road and Lindsay Road?
This project will only construct new traffic signals for the traffic interchange ramp intersections at Lindsay Road just north of Zanjero Park.
