Drivers will encounter lane restrictions beginning today, April 8, along both Loop 101 off-ramps at 51^st Avenue, state transportation officials said.

A city of Phoenix waterline project will require restrictions for a week before the ramps are closed from Monday, April 15, until late August.

The city has scheduled the following restrictions for its work at the Loop 101 interchange with 51st Avenue:

East- and westbound Loop 101 off-ramps at 51st Avenue will be limited to right turns through midnight Sunday night, April 14. Drivers will not be able to make left turns onto 51st Avenue. 

The east- and westbound Loop 101 frontage roads will be narrowed or closed at times in areas near 51st Avenue. 51st Avenue also will be narrowed in either direction near Loop 101.

Ramp closures scheduled: Both Loop 101 off-ramps at 51st are scheduled to be closed from early Monday, April 15 (by 5 a.m.) until Saturday, Aug. 24. The city’s schedule is subject to change, due to factors including progress made on the waterline project.

Detour: Freeway drivers can consider exiting Loop 101 at 59th Avenue and traveling south before turning east on Union Hills Drive to reach 51st Avenue.
