PITTSBURGH (AP) - Pittsburgh's Liberty Bridge has reopened with traffic restrictions, weeks after a construction fire closed the span for repairs.

PennDot has imposed a 9-ton weight limit on the bridge, meaning buses and large trucks can't use it. Three lanes of traffic will be open during peak travel times, and two lanes will be maintained overnight.

Workers have finished temporary repairs to realign the damaged lower cord. But crews will continue repairs on weekdays and weekends, shutting the bridge down, if needed, on weekends.

The fire began Sept. 2 on plastic pipes and a construction tarp as crews were cutting steel as part of an $80 million reconstruction project. The fire damaged a crucial support beam. Plans for permanent repairs are still being worked out.
