The eastbound offramp on Interstate 84 at the Broadway exit will be closed between 11 p.m. Sunday and 3 a.m. Monday.
The closure will allow Idaho Transportation Department crews to install a guardrail.
Motorists wanting to get off the freeway at Broadway will be directed to the Gowen exit and then rerouted back west to the Broadway exit.
ITD is replacing the Broadway Avenue Interchange with one that will accommodate higher traffic volumes and more lanes on I-84.
Construction updates will be sent via email and posted on the project website at: www.itd.idaho.gov/BroadwayInterchange. To sign up for email construction updates, contact ITD at email@example.com, visit the project website or call (208) 334-8005.
The project is expected to be complete by late 2015.
