A minor traffic switch is scheduled to take place during the evening hours on Sunday, May 3. Southbound traffic will be shifted to the newly paved northbound lanes between Center Street and Road 1 South. The switch will be clearly marked. Please remember to use extra caution while traveling through the construction zone for the safety of the crews and other motorists.
Business driveway maintenance
Concrete crews are diligently working to complete business driveways while maintaining access on the west side of SR 89. Business access is clearly marked throughout the project limits with “Business Access” signs to help direct traffic.
Excavation work continues
Roadway excavation work continues from the roundabout at Road 4 South/Outer Loop Road to the northern limits of the project. This work is preparation for building an additional southbound lane. This is being completed within the ADOT right of way and is not expected to affect traffic.
Progress Report
As of late April, construction was progressing as scheduled and with minimal impacts to traffic. Crews are finishing up Phase 1 of construction which included additional northbound lanes; construction of the roundabout at Road 4 South/Outer Loop Road; installation of a new waterline; improvements to business access driveways and curb and gutter on the east side of SR 89; box culverts; and utility relocation.
The project recently began work on the second phase of construction which includes additional southbound lanes; installation of a new storm drain; improvements to business access driveways and curb and gutter on the west side of SR 89; and completion of the roundabout. Construction is still anticipated to complete on time in late 2009.
There have been minimal affects on traffic through construction to date. On occasion, traffic was slightly more congested than usual due to traffic switches and unexpected accidents north and south of the construction zone on SR 89. Safety is the number one concern of ADOT and the construction crews will continue to manage a safe working environment for motorist and crew members.
The road will be widened from two lanes to four lanes.
Traffic signals will be installed at Road 2 South.
Road 1 South will be improved to allow for a future signalized intersection.
A roundabout will be built at Road 4 South.
Curb and gutter will be installed along the edge of the road, providing improved drainage for adjacent businesses.
A raised median will be installed down the center of the road to provide controlled left turns for safer access to businesses.
A new 18 inch ductile iron waterline will replace the existing 12 inch steel line under the road.
Install a 48 inch storm drain down center of SR 89 to improve drainage.
At this time construction will involve minimal traffic impacts as the majority of the work will be done off the roadway to construct the additional lane on the east side. ADOT has no daytime lane restrictions; some lane restrictions may occur during night work between 8 p.m. and 6 a.m.
Construction will be divided into three phases. Phase one will run from August 4, 2008 through winter 2009. Phase one will include construction on the roundabout at Road 4 South, widening of lanes on the east side of SR 89 between Center Street and Road 4 South, widening of the west side south of Road 4 South, and installation of a new 18 inch ductile iron water main. Night work will be required to install some portions of the water main. Phases two and three will follow shortly after the completion of phase one. More information is available regarding construction area phasing.
