Paving and ramp work continues on Interstate 10 between Valencia Road and Rita Road in Tucson

Daytime work hours begin Friday due to lower nighttime temperatures

The Arizona Department of Transportation continues repaving a segment of Interstate 10 in Tucson. Crews will intermittently close one lane and the entrance and exit ramps on eastbound and westbound I-10 from Rita Road to Valencia Road until mid-November 2012.

During the final weeks of construction, warmer weather is required while the upper layer of pavement is applied; therefore beginning Friday, Oct. 19, work crews will work during daytime hours to complete the project.

Wednesday, Oct. 24
The following work will take place from 6 a.m. to 4 p.m.:
• The left lane of eastbound I-10 will be closed from Valencia Road to Rita Road.


The Ashton Company, Inc. under contract to the Tucson Department of Transportation (TDOT) is beginning work on the Kino Parkway and 22nd Street Intersection Improvement. This work consists of replacing the existing intersection with a Single Point Urban Interchange (SPUI) and extending Kino Parkway over 22nd Street. 22nd Street will be widened to 6 lanes with dual left turn lanes and right turn lanes at the Kino Parkway intersection. Public art will also be included in this project and integrated into the new bridge and lighting design.

On Monday, October 8, 2012, the median lanes of Kino Parkway between Aviation Highway and 29th Street will be closed to allow crews to do tree salvage and clear and grub activities. Traffic control will be removed at the end of each work day. This work is expected to be complete on November 8, 2012.

Additionally, crews will begin waterline relocation work on 22nd Street from Cherrybell Stravenue to Kino Parkway. There will be intermittent lane closures during this work for eastbound traffic.

Crews will be working from 6:30 a.m. to 3 p.m.

Rillito River Park Drainage Improvements Near Swan Begin Oct. 3

Pima County Regional Flood Control District (RFCD) announces construction of north bank drainage improvements of The Loop on the Rillito River, just west of Swan Road through the Fletcha Caida Wash. The construction is scheduled to begin on Wednesday, October 3, and will continue until the end of October.

The Loop multi-use path in the construction area will remain open, but travel restrictions may be present intermittently. Bicyclists are asked to use caution and slow down through the construction zone for safety purposes and as a courtesy to other River Park users.

Signs will in place on The Loop alerting users about the construction.

"The intent of the project is to reduce flooding in this low-lying area," says John Spiker, Civil Engineer Manager with RFCD. "The project will reduce the water, mud, and sediment that collects on the path after storms."

The Loop is 55 miles of car-free paths being developed around metropolitan Tucson, with links to Marana and Oro Valley, for Pima County residents and visitors on foot, bikes, skates and horses.

The Loop connects the Rillito River Park, the Santa Cruz River Park, the Julian Wash Greenway, the Harrison Greenway and the Pantano River Park. The Loop connects to parks, trails, bus and bike routes, workplaces, schools, libraries, restaurants, hotels and motels, shopping areas, and sports and entertainment venues.

State Route 79 between Oracle Junction and Florence, between mileposts 111 and 128

The project will include a chip seal coat to improve asphalt conditions and restriping the roadway. Work is expected to last approximately two months, beginning Tuesday, September 4.

During the project, drivers can expect lane restrictions and reduced speed limits through the project corridor. Pilot cars will be used when the roadway is narrowed to one lane. Drivers are reminded to slow down,proceed through the work zone with caution and be alert for construction equipment and personnel.

State Route 90 bridge over the San Pedro River east of Sierra Vista in Cochise County.

Motorists traveling in the area will see restrictions and temporary traffic signals in place beginning Thursday, Sept. 27 to allow crews to prepare the existing bridge for replacement.

The $7 million project to replace the 57-year-old bridge is scheduled to be completed in 18 months, with a six-month construction shutdown from April 1, 2013 until October 1, 2013 to avoid disturbing the nesting season of migratory birds in the San Pedro Riparian National Conservation Area.

The new bridge, located near mile post 329 and one mile west of High Knoll Road, will feature wider travel lanes, emergency shoulders, new highway approaches and will be six feet higher than the existing bridge.

During each of the six-month construction periods from October through March, motorists on SR 90 will share a single lane controlled by temporary traffic signals.

The temporary signals will regulate traffic around the clock during construction. Delays of six to eight minutes are anticipated with the potential for waiting times as long as 15 minutes during peak travel times.

Some overnight closures of SR 90 will be necessary during the course of construction to safeguard motorists during certain work, requiring detours on State Route 92 and State Route 80. ADOT will provide advance notice of when those overnight closures will be in effect.

During the first six-month phase of construction, crews will replace the eastbound portion of the bridge, with traffic sharing a single lane on the westbound portion of the existing bridge.

Workers will be on site from 6 a.m. until 5 p.m. weekdays.

Crews will demolish the southern half of the existing bridge and construct a new bridge that will be six feet higher above the San Pedro River to meet 100-year-flood plain requirements. The work will require removal and trimming of a limited number of trees in the work area to allow for crews to construct the new bridge. New trees will be replanted in the area to replace the trees that need to be removed.

Construction of the south side of the new bridge - a 17-foot-wide section with a 13-foot travel lane - is scheduled for completion before April 1, 2013, when construction will take a six-month break for the nesting season for the protected Southwestern Willow Flycatcher and other migratory birds.

During the six-month construction hiatus, traffic will use one lane in each direction - eastbound traffic on the newly constructed bridge and westbound on the old bridge - and the traffic signal will not be in use.

On Oct. 1, 2013, work will resume with demolition of the north side of the old bridge and reconstruction of the rest of the new 44-foot-wide bridge. The signal will once again control traffic sharing a single lane on the completed portion of the new bridge.

During construction, pedestrians will not be permitted to cross the bridge for safety reasons and bicyclists are encouraged to avoid using the bridge. Also, the hiking trail that originates at the nearby San Pedro House and passes beneath the SR 90 bridge will be closed during construction. Other trails in the area will not be affected.

When the project is complete in spring 2014, the new bridge will feature two 12-foot travel lanes with 10-foot shoulders for emergency situations and for use by bicyclists.


Starting Monday, October 22, through Friday, October 26, 2012, the Pima County Department of Transportation, Regional Transportation Authority and their contractor, Ashton Company, will be closing Mona Lisa Road at Magee Road to remove existing asphalt and reconstruct the intersection for final paving.

The work will begin at 8 a.m. Monday, the intersection is expected to reopen on Friday, October 26, 2012, at 5 p.m. Area traffic will be directed to proceed south on Mona Lisa to Ina Road for access.

This closure is part of Phase I (Shannon Road to La Canada Drive) of the Cortaro Farms Road/Magee Road: Thornydale Road to Oracle Road improvement project.


On Tuesday, October 23 through Friday, October 26 2012, between the hours of 7 a.m. and 4 p.m., Pima County Department of Transportation, will be performing a crack seal paving treatment on Houghton Road from Tanque Verde Road to Speedway Blvd. Work is expected to be completed in four (4) days.

Traffic will be directed through the work zone area by a pilot car.
