The Lakina River Bridge was damaged earlier this week when a vehicle hit an overhead truss.
Most passenger cars and light duty pickup trucks weigh less than the 6,000-pound limit, according to the department. The weight of a vehicle is listed on the vehicle registration and inside the driver side door.
DOT&PF employees will be stationed at the bridge to monitor the size of loads crossing it.
Restrictions are in place until a repair plan is implemented.
Updates are available by calling 511 or visiting 511.alaska.gov.
