Portions of the Loop 202 Red Mountain Freeway and state Route 143 will close this weekend.
Westbound Loop 202 will close between Gilbert Road and Country Club Drive from 3 a.m. to 5 p.m. Saturday to install an overhead message sign.
Northbound Route 143 will close from Broadway Road to Washington Street from 9 p.m. Friday to 5 a.m. Monday for pavement improvements. That will block access to Phoenix Sky Harbor Airport from Route 143.
