Construction Project US 12/18 & County AB Interchange
March 6, 2023 - Late October 2023
Over the last few months, construction has been well underway along Millpond Road and the routes to the Dealership. The purpose of this project has been "to reduce the overall number and severity of crashes, decrease travel time delays,..." among other noted advantages.
As of October 26, the right turn onto the roundabout for Millpond Road is NOW OPEN using EXIT 268! When exiting the interstate or coming from the Beltline, you no longer have to take the long way to EXIT 269 and double back.
The left turn lane from 12/18 Westbound and the previous intersection have been permanently closed and will no longer be an option to access the Dealership.
All exits are open now and besides some residual road work, the paths to the Dealership are complete. Most GPS services have been updated to reflect the changes made for EXIT 269, including Google Maps, while the exit onto Millpond Road has not. See below for a visual of that exit.
Thank you for your patience during this process. Enjoy the rest of Riding Season - See you on the road!
EXIT 142B (12/18 to Cambridge) on Northbound/Southbound I-39/90 have been REOPENED.
