JACKSONVILLE, Fla. -

The Mathews Bridge will have lane closures in both directions from 8 p.m. Friday to 5 p.m. Saturday to replace existing median barriers at each end of the bridge.

The new barriers are removable and will be used in emergency evacuations.

A foundation for the new removable guardrails is scheduled to be built this weekend, according to the Florida Department of Transportation. Placement of the guardrails is tentatively scheduled for the following weekend.

All work is weather permitting.

Motorists should use extreme caution while traveling through the area and keep in mind that speeding fines are doubled in construction areas when workers are present.
