Back in February, IndyGo accelerated construction for the upcoming Red Line bus rapid transit system.

The plan was intended to ramp up construction on the 13-mile corridor from Broad Ripple to the University of Indianapolis to shave four months off the construction schedule in order to open this summer. Now there are some firm dates for when the public can expect the launch.

The final day of construction is scheduled for July 31, when all projects will need to be wrapped up.

According to Lauren Day, spokeswoman for IndyGo, August will be reserved to work out any kinks and run training, allowing bus operators to drive the route. Day said a practice bus platform was built at the IndyGo facility so operators can get the hang of the elevated platforms at each of the stations.

Barring any unforeseen circumstances, Day said the Red Line will officially open on Sunday, Sept. 1. She said Sundays historically have the lowest ridership and are usually the day IndyGo launches new routes.

Labor Day is Sept. 2, so it will allow even more time for riders to learn how to ride the Red Line before the start of the work week.

At the April IndyGo board meeting, the board voted to approve nearly $5 million in construction change orders and professional service amendments for the Red Line. Bryan Luellen, vice president of affairs for IndyGo, said the approval only moved contingency funds into the contracts, and does not increase the $96.3 million overall budget of the project.
