Construction of the Transform 66 Outside the Beltway Project began in April 2018. Our goal is to minimize disruption to commuters as four lanes of traffic will be open during peak periods, with the exception of a portion of I-66 near Gainesville which will have three lanes during peak periods. Lane closures will take place in off-peak daytime and overnight hours. With day and night activity in the work zone, motorists should drive safely and stay alert at all times.

Throughout the project, you can find updated traffic information on and through our social media outlets.
