Chipotle Mexican Grill, the popular, national burrito chain, and Baggins, the popular Tucson sandwich chain, are moving into one of Marana's busiest retail corridors.

Both restaurants are expected to open in the next couple months across the street from one another on West Arizona Pavilions Drive off Interstate 10 and West Cortaro Road.

Chipotle will take over the retail space that was most recently home to Payless Shoe Source at 5940 N. Business Park Drive. Construction has been ongoing since early December and the restaurant is expected to open sometime in the next couple months, company officials said.

• Construction just got started on the 2,300-square-foot-space where Baggins will serve its menu of gourmet sandwiches and salads beginning sometime in early February, said Baggins Vice President Sunny Bravin. This will be Baggins' ninth Tucson location.

Bravin said the timing is right to move into Marana, which has seen remarkable growth in mostly chain restaurants in the I-10/Cortaro Road corridor in the past several years. Among the restaurants already operating there is Chili's, Native Grill & Wings, Texas Roadhouse, Cracker Barrel and a handful of fast-food outposts including In-N-Out Burger and Panda Express.

Dunkin' Donuts opened a store at 8090 N. Cortaro Road across the driveway from Panda Express in late summer. In early November, Village Inn, known for its breakfast specialities and homespun comfort food, opened at 5955 W. Arizona Pavilions Drive.

"That area is booming over there," said Bravin. "I think that's just been an underdeveloped area for our clients. We have a lot of customers (from Marana) who come to our Oro Valley and Oracle Road stores."
