I-15 traffic shift at Riverton Road
BLACKFOOT – The Idaho Transportation Department has shifted lanes to offer travelers one southbound lane and two northbound lanes separated by a median on Interstate 15 between Exit 89 and Exit 93. Traffic had previously been crossed over to the northbound lanes with little separation between oncoming traffic following a collision last week that badly damaged the Riverton Road Bridge.
ITD engineers estimate that southbound I-15 will remain one lane underneath the bridge and that the bridge itself will remain closed until next spring.
Motorists are encouraged to use 511.idaho.gov for the latest traffic conditions.
