Work on Project Neon will enter its final phase this weekend.
The third and final phase of the main Project Neon project includes a widening of Interstate 15 from the U.S. 95 interchange to Sahara Avenue.
The construction will occur overnight this weekend to not interfere with the NASCAR event.
Sunday morning from midnight to 7 a.m. southbound U.S. 95 will be closed at Decatur Boulevard.
The freeway onramps at Decatur, Valley View Boulevard, Rancho Drive and Martin Luther King Boulevard to southbound U.S. 95 will all be closed from 10 p.m. Saturday to 8 a.m. Sunday.
The bulk of the Main Event work kicks off Monday morning, which will reduce I-15 from Sahara to Washington Boulevard to three lanes in each direction.
