The southbound lane of National Avenue in the 1200 block will be closed from 9am-5pm Wednesday, September 10; Thursday, September 11; and Friday, September 12. Public Works crews will be installing new gutter along the roadway after a water/sewer service installation last week. Then, they'll be installing a brand new sidewalk. Detours will be set up for those traveling south. We will reopen this section of the road as soon as possible once the project is complete.
