Whether you're behind the wheel, biking it or taking the bus, here are some transportation changes to know about this week.

Magee Road will be closed at the Cortaro Farms-Shannon Road intersection today through Saturday.

During the closure, crews will install an underground drainage system, reconfigure the intersection and do paving prep work, according to a Pima County Transportation Department press release.

Drivers will be detoured west to Thornydale Road.


Expect up to 15-minute delays on westbound Interstate 10 east of Tucson near Marsh Station Road this week.

Traffic will be down to one lane, and the speed limit will be reduced to 45 mph as crews make preparations for removing the old Union Pacific Railroad bridge.


Several sections of "The Loop," a long bicycle-pedestrian path looping the city, are under construction for widening and other improvements.

Widening work between Ina Road and the I-10 frontage road will close the popular path Monday through Thursday for the rest of the month, but it will be open weekends.

Crews are resurfacing and restriping the path between Camino de la Tierra and La Cholla Boulevard on the south bank of the Rillito River, so use the north-side path.

Later they'll pave and stripe between Dodge Boulevard and Alvernon Way on the south bank and repave between Alvernon and Craycroft Road on the north bank.

Construction of a new section is starting near Augie Acuña Los Niños Park on the south side, and the underpass at Kolb Road will be done in late spring.


Expect shorter waits between buses on two major Sun Tran bus routes.

Bus service on Route 7, which runs along 22nd Street, will be available every 15 minutes instead of every half hour. And on Route 16, which runs up and down Oracle Road-10th Avenue, buses will stop every 10 minutes between the Laos and Tohono transit centers, instead of every 15 minutes.

The updated Ride Guide, which includes more changes, is available throughout Tucson.


Q: "What's the projected completion date for La Cañada's widening from Ina to River?" asks Gerry Lawford.

A: There's another year to go.

"The crews are continuing to make good progress," said Rick Ellis of the Pima County Transportation Department. These days crews are working on a variety of tasks, including utility work, clearing, grading, drainage work and retaining-wall work, he said.
