Construction work on the Wilson Bridge Project will cause delays this weekend on the Capital Beltway.
Many of the projects are on major commuter routes heading into the District.
A spokesperson for the Virginia Department of Transportation calls it "one of the busiest construction seasons we've had in a long time."
Leading the list is the completion of the Intercounty Connector interchanges over heavily traveled Route 29 and Briggs Chaney Road in Montgomery County.
Then there's all the construction on the Capital Beltway around Tysons Corner, Va., which will continue through the summer. Beginning this month, workers will begin shifting high-occupancy toll lanes from the median to the outer lanes and rebuilding more than 50 bridges and overpasses.
Meanwhile, in D.C., the 14th Street Bridge rehabilitation project is still ongoing, creating rolling slowdowns in peak and off peak hours.
