The National Park Service will be making temporary repairs beginning Tuesday to the brick crosswalk at the four-way intersection of the George Washington Parkway and the  northbound and southbound Mount Vernon Memorial Highway.

Crews will remove the cracked and broken bricks, replace the sand base, and install new bricks.

The work will take place in three phases, and there will be partial closures of the intersection as each section is being repaired. There will be flagmen to direct traffic around the repair area, which may cause some traffic delays.

The work will be performed from 9:30 a.m. until 2:30 p.m. weekdays and is expected to be completed by Friday.

Permanent repairs of the crosswalk are planned for August 2013, pending federal approval of project funding.
