The Arizona Department of Transportation (ADOT) is planning a major road improvement project for Inter-state 40 east of Holbrook between mileposts 290.30 and 297.
The construction work will begin approximately four miles east of Holbrook, and will encompass the inter-changes with Keams Canyon/State Route 77 and the overpass at 292.82, and the Sun Valley Road underpass at 294.55.
According to ADOT, the pavement in the construction zone has deteriorated with age, and is buckling and cracking.
Due to winter weather conditions, the construction will take place over two seasons, with a total project time of six to seven months. The first phase will begin in October 2013 and run for approximately two months. In this phase, ADOT will be replacing guardrails, fencing and bridge guardrails.
The second phase will begin in May 2014, and will most likely include repaving, restriping, shoulder buildup and Sun Valley Road joint repairs.
One lane of traffic will be kept open in each direction during the construction work, but motorists should expect much slower speeds to be allowed.
Some specific work on the project includes:
* Removing and replacing the existing travel lanes on I-40.
* Building up the shoulders with millings from milepost 290.30 to milepost 291.30 and as needed through-out the rest of the project.
* Installing ground-in rumble strips throughout the entire project.
* Removing and replacing guardrails to meet height requirements throughout the project.
* Replacing the guardrails at the turn radii of the Sun Valley Road on and off ramps with concrete barriers.
* Replacing the bridge joint on the Sun Valley Road Bridge.
* Replacing existing roadway delineators throughout the entire project.
* Removing and replacing existing right-of-way fence throughout the project.
Renee Mulholland of HDR Engineering, Inc. in Phoenix said the planned work is standard highway repairs.
“The only way the public will be impacted is through slower traffic,” said Mulholland. She said no private land was being taken for the project, and all the repairs will be to the existing highway and interchanges.
The public is invited to submit any comments or concerns by Monday, Nov. 26, by mail to Renee Mulholland, HDR Engineering, Inc., 3200 E. Camelback Road, Suite 350, Phoenix, Ariz. 85018; by e-mail to or by fax to (602) 522-7707.
