UPDATE (Friday 10:21 a.m.) - Authorities have cleared the scene of the accident, but there are still special conditions on the road, according to MDT.
Due to the accident on Thursday, there are reduced speeds in effect on I-15 southbound on the Marias Bridge. 45 miles-per-hour is reportedly the current speed limit in effect for the area.
An MDT official says the reduced speeds were implemented due to the bridge missing some railing as a result of the accident. Water barriers have been installed while repairs are underway, though it is not known how long it will take to replace the railings.
