The latest full closure of Interstate 15 near downtown is slated to snarl traffic this weekend.

I-15 south between the Spaghetti Bowl interchange and Charleston Boulevard will be closed from 10 p.m. Friday until 5 a.m. Monday, the Nevada Department of Transportation announced Monday.

Along with the stretch of I-15 shut to traffic, the following freeway ramps will be closed between 8 p.m. Friday and 6 a.m. Monday:

— U.S. Highway 95 northbound to I-15 southbound.

— The D Street onramp to I-15 southbound.

— The U.S. 95 northbound offramp to Martin Luther king Boulevard.

— The I-15 northbound offramp to Martin Luther King Boulevard.

All I-15 southbound traffic will be detoured to U.S. 95 northbound onto Martin Luther King Boulevard, re-entering I-15 southbound from the new Pinto Lane slip onramp.

The temporary closure is needed for completion of work on the high occupancy vehicle flyover structure as part of Project Neon, a nearly $1 billion, 4-mile-long widening of I-15 from the U.S. 95 interchange to Sahara Avenue that began in 2016.

The closure will be the last of the I-15 occurrences associated with the project until the summer, when asphalt overlay is placed along the entire project’s scope, NDOT said.

Project Neon is 90 percent finished and scheduled for substantial completion this summer.
