Middle/Summer/Miller Intersection

Go to the final design plans for the intersection. Please note that due to issues encountered in the field during construction, minor modifications were made to some of the crosswalks, tip down ramps and pavement markings to ensure compliance with ADA standards. A final “As-Built” plan will be posted on this page once the project is completed. This “As-Built” plan will include the changes made in the field during construction.

This project includes the realignment of the intersection to provide safer, slower travel and better sight distance. The plan is to replace the existing outdated traffic signal equipment with a new signal that meets current design standards. New mast arms, signal heads, pedestrian signals, accessible curb ramps, signal detection and signal controller will be included. Modifications to the pavement markings and lanes are also proposed.

This project and the three design alternatives was discussed at the November 29, 2023 Parking & Traffic Safety Committee meeting. Go to the P&TS meeting packet for details. Go to the design concepts.
