LAS VEGAS -- Those commuters who use the airport connector tunnel during the overnight hours will need to find an alternate route Monday.

From 11 p.m. Monday until 5 a.m. Tuesday, county aviation crews will be installing new cameras in the tunnel. They will close the center and left lanes to through traffic.

Also from 11 p.m. Tuesday to 5 a.m. Wednesday, the southbound traffic will be limited to one lane for the same reason.

While it may cause a slight delay in the morning commute, officials said the work should only cause a slight delay in traffic.
