At least two big rig trucks were involved in a collision early Monday morning on northbound Highway 99 in Merced, blocking both northbound lanes and slowing down traffic south of R Street.
Officials say both trucks were destroyed in the crash, which resulted in minor unknown injuries.
Northbound lanes were completely shut down between 1:30 and 5 a.m.
Both lanes are now open, but officials say drivers can expect delays until traffic dissipates and gets back to normal.
