Cone Zone 8/7: New week, new construction ...and old construction

MODERN STREETCAR
Broadway and Church Avenue Intersection

On Monday August 6, 2012, at 6 a.m. the Sun Link Tucson Streetcar contractor will begin necessary repair and replacement of a sewer line that extends across Broadway between Congress and Stone Avenues. The condition of the sewer lines and manholes require immediate and extensive underground work. The boundaries of the work area and safety considerations require Broadway to be completely closed between Church and Stone Avenues. The closure will be in effect 24 hours a day through mid-September. The traveling public should be aware of this information:

* Access to the underground parking garage for tenants of 1 South Church Avenue will be maintained.

* Broadway eastbound traffic will be detoured south on Church Avenue to Ochoa Street or McCormick Street, east to Stone and Scott Avenues, and north back to Broadway. Tucson Police officers will be on-site to assist with directing traffic.

* Four-way stops will be in place at the intersections of Ochoa Street at Stone Avenue and McCormick Street at Stone Avenue.

* Turn movements from eastbound Broadway to northbound Church will be maintained during daytime hours. Intermittent nighttime restrictions may be in place.

* Parking will not be allowed along Church Avenue between Broadway and Jackson Street while the detour is in place.

* Sidewalk access will be maintained at all times, however, north and southbound Church Avenue pedestrians must use the crosswalk on the west side of the intersection to cross Broadway while intersection work is under way.

Fourth Avenue and University Boulevard

This area of the project includes 4th Avenue from the 4th Avenue underpass to University Boulevard, University Boulevard to Main Gate Square, and Park Avenue to 2nd Street. Traffic control in this area is as follows:

From 3 a.m. on Wednesday, August 8, until 3 a.m. Monday, August 13, the intersection of Euclid Avenue and University Boulevard will be closed. The temporary intersection closure allows the contractor to place rail, pour the concrete track slab and pave across the intersection.

Pedestrian access will be maintained during the five-day intersection closure.

Access to surrounding businesses, parking and parking garages will be maintained.

Electronic message boards will be in place to help direct motorists around the work area.

Weather permitting, on Monday, August 13, the intersection will be open to one travel lane in each direction.

The contractor will work extended hours and weekends during this operation.

TANGERINE ROAD STRIPING

Beginning August 6 and continuing through August 10, between 9 a.m. and 3 p.m. each day, construction crews will be completing pavement markings on Tangerine Road from the Union Pacific Railroad to Thornydale Road. Motorists may be subject to reduced speeds and detours to accommodate this operation.

For your safety and that of construction workers, please comply with all traffic control devices, flagging personnel and/or detour signs.

Please be aware of construction activities during the course of this project. Your travel time may increase, so please adjust your schedule accordingly. Construction may restrict traffic lanes and create congestion. Taking alternate routes is suggested.

If inclement weather or other events cause delays, the work may be rescheduled without further notice.

Improvements to the Town of Marana's roadways may cause a temporary inconvenience. We appreciate your patience as we improve the community.

SILVERBELL ROAD DAMAGE FROM 100-YEAR STORM

Pima County Regional Flood Control District (RFCD) and the Department of Transportation Maintenance Operations Division joined forces to quickly assess and repair damage to Silverbell Road after Sunday's extreme storm event.

On July 29, 2012, Idle Hour Wash peak flow was 5,800 cubic feet per second, equal to a 100-year storm, according to RFCD evaluation of high water marks. Based on comments from neighbors and silt deposits, at least 600 feet of Silverbell Road was covered by flowing water.
Rain gauges upstream from Silverbell Road in the Idle Hour Wash watershed recorded 2.5 to 3.8 inches of rainfall in two to three hours, with most rainfall occurring in the first hour. It is the area's most damaging storm since the floods of 1993.

The tremendous surge of water eroded the embankment and soil beneath Silverbell Road, approximately .9 miles north of Sunset Road. Pima County Sheriff Department immediately closed this section of Silverbell Road, between Sunset Road and Panorama Road. The road remains closed for repairs; however, local residents still have access to neighborhood streets. This section of Silverbell Road is expected to reopen by Wednesday, August 8. In the event of mechanical failure or inclement weather, the construction schedule is subject to change.

UPDATE SABINO CANYON ROAD/TANQUE VERDE ROAD

Beginning Monday, August 6, 2012, crews from Southern Arizona Paving, under contract with the Tucson Department of Transportation (TDOT), will adjust the water valve covers and manhole covers flush with the new asphalt. Work is expected to be complete by Friday, August 10, 2012. Crews will be working from 6 a.m. to 3 p.m.

During this work, concrete will be poured around the covers and barricades will be in place for 24 hours to allow the concrete to cure. Concrete curing signs will be in place to notify the traveling public why the travel lane restrictions are in place. Business access will be maintained at all time.

This is the final phase of the construction for the intersection improvement project.

Please use caution when driving, bicycling or walking in the work area. Please obey all traffic control devices and watch for construction personnel and equipment in the work zone.

WORK ON I-10 BRIDGE OVER SR 90

Motorists on eastbound I-10 and SR 90 will be detoured around the interchange project

Motorists traveling on Interstate 10 and State Route 90 near Benson will encounter full closures of both highways over the coming weekend as the Arizona Department of Transportation pours the deck for the new eastbound I-10 overpass bridge in western Cochise County.

Beginning at 6 p.m. Friday, Aug. 10, all eastbound I-10 traffic will exit at the SR 90 interchange (Exit 302) and return to I-10 on the other side of the bridge construction project. The closure will remain in effect until 6 a.m. Sunday, Aug.12, when the left lane of eastbound I-10 will reopen to traffic with a 45 mph posted speed limit.

The other lane of eastbound I-10 will open at 6 a.m. Monday, Aug. 13 and regular speed limits will resume.

State Route 90 will be closed to traffic in both directions at I-10 from 6 p.m. on Friday, Aug. 10, until 6 a.m. Sunday, Aug. 12. During this closure, the following detours will be in effect:

• Westbound I-10 traffic wishing to access eastbound SR 90 will continue five miles to Mescal Road (Exit 297) and return to eastbound I-10.

• Eastbound I-10 traffic wishing to access westbound SR 90 will continue two miles to Ocotillo Road (Exit 304) and return to westbound I-10.

• SR 90 traffic wishing to enter westbound I-10 also will take eastbound I-10 to Ocotillo Road and return to westbound I-10.

SWIFT TRAIL IMPROVEMENT AT NOON CREEK

Federal project will replace old bridge and improve drainage on highway to Mount Graham

The Federal Highway Administration will begin construction of a new concrete culvert at Noon Creek on State Route 366 next week as work continues toward making improvements at two locations on the scenic Graham County highway.

Crews will continue building a new bridge at Wet Canyon that has been under construction since February at the same time they begin work on Monday, Aug. 6 to replace two older pipe culverts at Noon Creek with a single larger drainage culvert.

Motorists traveling up the popular highway to Mount Graham, known locally as Swift Trail, will take a short detour around the construction site, which is located near milepost 121.

FHWA crews will install a concrete barrier to provide protection from traffic while they construct the new culvert designed to reduce the potential for highway flooding.

Temporary traffic signals now in use at Wet Canyon will be moved to Noon Creek in late August, when traffic in both directions will begin to share a single lane while crews install the culvert.

At Wet Canyon, located near milepost 124, crews are scheduled to pour the concrete retaining walls for the new bridge, which will provide motorists with a wider turn and better visibility than the existing historic bridge. The older bridge will remain for pedestrian use.

The abutments for the new bridge are complete and in mid-August, FHWA crews will begin construction of the deck.

Traffic delays in both locations are expected to be minimal.

Work on both locations is scheduled for completion in early October 2012.

ADOT CONSTRUCTS NEW US 70 GILA RIVER BRIDGE

Motorists traveling on US 70 through the San Carlos Apache reservation have seen lots of bridge improvements being made in the past year.

The Arizona Department of Transportation has been busy on the highway bridge over the San Carlos River just east of Globe and, more recently, the US 70 Gila River Bridge at Bylas.

As any motorist passing on the older bridge can tell you, the Bylas bridge - which is among the longest in Arizona's extensive bridge inventory - is going up quickly.
