CRITTENDEN COUNTY, Ark.- A spokesperson for the Arkansas Department of Transportation said the Interstate 40 bridge connecting Arkansas and Tennessee is closed after a crack was found during an inspection on the bridge. 

According to the ARDOT Twitter page, Tennessee highway crews are doing emergency maintenance on the Mississippi River bridge. 

ARDOT said traffic is being rerouted to I-55 as an alternate route. 

Tennessee I-40 westbound traffic should take the I-55 bridge across the Mississippi River to cross into Arkansas and then take Exit 4 to access I-40 westbound.

According to ARDOT, there is no timeline for how long the maintenance and closure will be.
