FLAGSTAFF, Ariz. - The Arizona Department of Transportation (ADOT) plans to close the westbound lanes of Interstate 40 (I-40), as well as the westbound on- and off-ramps at Cosnino Road, on Tuesday, June 30. The closure is part of a project to reconstruct portions of westbound I-40 from milepost (MP) 205 to MP 209.
All interstate traffic will be routed onto the eastbound lanes, with one lane for each direction of travel. The closures are expected to be in place through October. Prior to June 30, drivers should plan for intermittent lane closures on both eastbound and westbound I-40.
The eastbound I-40 on- and off-ramps and Cosnino Road above I-40 will remain open throughout the project's duration. During the wetbound ramp closures, ADOT recommends using the nearest interchanges to the east (Winona) and west (Walnut Canyon) as detour routes.
Traffic restrictions will be in effect 24-hours per day throughout the project's duration. Speeds in the project area are reduced to 35 mph, and the I-40 travel lanes are restricted to widths of 16 feet or less. ADOT expects to complete this phase of the project by November after which all lanes and ramps will be opened. Additional work will be necessary in summer 2010, which will require short-term closures of the westbound on- and off-ramps and I-40 travel lanes. All dates and hours above are subject to change, and some weekend work may be necessary.
The $5.8-million project includes reconstructing westbound I-40 by taking out some of the grades, realigning the westbound on- and off-ramps at Cosnino Road, installing new guardrails, pavement markings, signing and other related work. This project is being funded by the American Recovery and Reinvestment Act (ARRA), which is part of federal funding given to the state for economic recovery.
Motorists must obey all posted restrictions throughout the project area. Message boards and other traffic signs will provide additional construction details. ADOT and the contractor appreciate the public's patience during construction. For more information, call the project's toll-free hotline at 1-866-659-0656 or visit www.FlagstaffRoadConstruction.com.
