New westbound I-10 lanes to open at Ina Road in Marana
-
ADOT
New westbound Interstate 10 lanes at Ina Road in Marana will open to traffic this weekend, another step forward for a two-year project aimed at improving traffic flow and safety at the busy interchange, officials said.
For most of the past year, both directions of I-10 between Orange Grove and Cortaro roads have been sharing the future eastbound lanes, separated by concrete barrier, as the Arizona Department of Transportation constructs a new Ina Road interchange to serve the growing area. I-10 will remain three lanes in each direction after the shift.
On westbound I-10, the right two lanes will be closed near Ina Road beginning at 8 p.m. Saturday, Dec. 8, to allow crews to move barricades and open the new travel lanes. The work is expected to be complete before 5 a.m. Sunday, Dec. 9.
The $128 million Ina Road interchange project, which began in late February 2017, includes new bridges carrying Ina over the Union Pacific Railroad tracks, eliminating the need for drivers to stop for the many trains that pass each day. Ina will be widened to two lanes in each direction from I-10 west over new bridges crossing the Santa Cruz River.
ADOT is overseeing the improvements, which are funded by the Federal Highway Administration, the Pima Association of Governments and the Regional Transportation Authority. The town of Marana is contributing $7.9 million toward the cost of the new Santa Cruz River bridges west of I-10.
The work is part of an ongoing effort to improve traffic interchanges on I-10 throughout the Tucson area. Similar improvements at the Ruthrauff Road interchange are scheduled to begin in summer 2019.
