Beginning Jan. 17, the I-15 southbound off ramps to Tropicana both ways will be closed.

The ramp to westbound Tropicana will be closed for about 9 months, and the flyover ramp to eastbound Tropicana will remain closed for approximately 18 months.

Tropicana will close in both directions between Dean Martin Drive and New York- New York from Jan. 22 to 30.

1-15 will close in both directions at Tropicana from 10 p.m. Friday, Jan. 27 to 5 a.m. Monday, Jan 30.

Crews will demolish and rebuild the current eastbound lanes of Tropicana over I-15 and Frank Sinatra Drive. Much of the flyover ramp from southbound I-15 to eastbound Tropicana will also be demolished and rebuilt, which is necessary so the road can be widened and raised to add capacity and increase safety.
