INDOT Making Intersection Improvements in Marion County

INDIANAPOLIS - The Indiana Department of Transportation is investing approximately $4.1 million in intersection improvements on local streets in Marion County ahead of major projects coming to the area. INDOT is engaging contractors to perform traffic signal upgrades and spot improvements to numerous Indianapolis area intersections to help reduce congestion and improve traffic flow and safety on routes that may experience increased traffic volume during major interstate construction.

INDOT is funding the total cost of the local improvements and coordinating the work with the Indianapolis Department of Public Works.

Signal Upgrades

The effort will modernize a total of 489 traffic signals in three different groups. Blue dots on the map below indicate intersections where traffic signals will be equipped with GPS time synchronization cards. The GPS cards will be installed to maintain accurate time clocks for each signal, enhancing synchronization between the lights. 

The second group of signals (red dots) will have cellular modems installed. The modems will also ensure time clock synchronization and have the capability to be controlled by INDOT's Traffic Management Center so that signal timing can be adjusted remotely. 

The third group of signals, represented by yellow dots, will have cellular modems installed as well as Closed Circuit Television (CCTV) cameras that can be viewed from the INDOT Traffic Management Center to help monitor for congested streets. The real-time video allows traffic technicians to make signal adjustments to accommodate for heavy traffic. Video is not recorded or archived.

Spot Improvements

Spot improvements, such as turn signals, median and curb alterations and turn lane additions, will reduce congestion at 11 intersections.

While contractors are making improvements, existing signal infrastructure will be tested at each location and repairs made where needed.

Signal upgrades and intersection improvements are proactive steps INDOT is taking to reduce congestion on city streets during major construction projects coming to Marion County. However, the upgrades will  remain in place after major interstate construction is complete as they will provide long-term safety and mobility benefits to the Marion County street network.

All work will begin this fall and is scheduled to be complete by Summer 2021.
