Construction crews were working on a "cap" over I-579, also known as the Crosstown Expressway, in Downtown Pittsburgh on Jan. 29, 2020.

Southbound I-579 will close to traffic in Downtown Pittsburgh between the Bigelow Boulevard overpass and the Center Avenue exit at night Monday through Saturday morning.

The expressway will close from 7 p.m. to 6 a.m. Monday through Thursday nights and from 7 p.m. Friday night to 10 a.m. Saturday morning.

Traffic may be reduced to single lane for northbound traffic, too.

Crews will continue installing box beams over I-579 that will require the closures and detours.
