The Indiana Department of Transportation announced Friday that it plans to upgrade 489 traffic signals in Marion County over the next year at a cost of $4.1 million.
INDOT said it would fund the total cost of the project and coordinate the work with the Indianapolis Department of Public Works.
The work is set to begin this fall and is scheduled to be completed by summer 2021.
The upgrades will fall under three different categories:
- Traffic signals will be equipped with GPS time-synchronization cards. The cards are expected to maintain accurate time clocks for each signal, improving synchronization between the lights.
- Traffic signals will have cellular modems installed. The modems ensure time-clock synchronization and can to be controlled by INDOT’s Traffic Management Center so that signal timing can be adjusted remotely.
- The third group of signals will have cellular modems installed as well as closed circuit television cameras that can be viewed from the traffic management center to help monitor for congested streets. The real-time video will allow traffic technicians to make signal adjustments to accommodate for heavy traffic.
INDOT did not say how many signals would receive each type of upgrade. A color-coded map of affected signals is available here.
INDOT said it is hiring contractors to perform the upgrades.
In addition, INDOT said “spot improvements” are planned for 11 additional intersections:
- Pennsylvania and Ohio streets: Change southbound bus lane to right-turn lane due to bus-route changes.
- Raymond Street and Kentucky Avenue: Install left turn signals on Raymond.
- Raymond Street and Southeastern Avenue: Alter median curb on Southeastern toreduce queue blockages.
- Southport and Bluff roads: Add railroad preemption at traffic signal.
- County Line and Railroad roads: New traffic signal with railroad preemption.
- Washington and New Jersey streets: Repair damaged signal conduit.
- Washington and East streets: Install pedestrian pushbuttons to cross east leg of Washington.
- Fall Creek Parkway: Restore lane control system from 30th Street to College Avenue.
- Interstate 70 and Harding Street: Convert northbound through lane to second left-turn lane at both ramp intersections.
- Interstate 65 and Keystone Avenue: Add second left-turn lane on the northbound exit.
- Washington Street and Southeastern Avenue: Remove center island to add westbound lane and prohibit left turns from Washington.
