The Nevada Department of Transportation will close northbound Interstate 15 between Spring Mountain Road and Sahara Avenue from 11 p.m., Sept. 5, until 5 a.m., Sept. 6, in downtown Las Vegas.
Additional ramp closures include the following:
• The west and eastbound Spring Mountain Road on-ramps to Interstate 15 northbound will be closed from 9 p.m., Sept. 5, until 6 a.m., Sept. 6.
• The Flamingo Road onramp to Interstate 15 northbound will also be closed from 9 p.m., Sept. 5, until 6 a.m., Sept. 6.
