Part of Interstate 235 is scheduled to close Friday night, one of two planned closures this month for road work projects along the highway, Oklahoma Department of Transportation officials said.

Starting at 7 p.m. Friday, north- and southbound lanes of I-235 between NW 36 and Interstate 44 will be closed as contractors hang steel beams for the bridge that carries NW 50 over I-235.

Ramps closed due to the work include eastbound I-44 to southbound I-235, westbound I-44 to southbound I-235 and the northbound ramp from NW 36.

Officials said the interstate is scheduled to reopen by 6 a.m. Monday.
