ADOT study identifies future US 93 traffic interchanges north of Kingman

Interchanges along U.S.

Highway 93 between Kingman and Hoover Dam were the subject of a Thursday hearing in Kingman.

The Arizona Department of Transportation held the hearing to discuss a preliminary study assessing existing and future access points along Highway 93.

The study includes potential traffic interchange locations that have been developed with the ultimate goal of making Highway 93 completely "access-controlled," with no access other than traffic interchanges with on and off ramps.

"This meeting is the first of two public hearings designed to share our project with the public," said ADOT District Engineer Sam Elters, who was on hand to answer questions at the meeting.

ADOT and Mohave County are working together to assess access points along the highway between the state Route 68 junction and milepost 17, south of Hoover Dam near Temple Bar Road.

The study identifies seven potential traffic interchanges located along US 93 at Temple Bar Road, White Hills Road, Pierce Ferry Road, Cottonwood Road, Windy Point Road, Old Highway 62 (Chloride Road) and Hermit Drive.

The study is being conducted by DMJM+HARRIS, an engineering consulting firm located in Phoenix, and a Technical Advisory Committee comprised of members from ADOT, Transportation Planning Group, ADOT Kingman Engineering District, Mohave County, Bureau of Land Management, Arizona State Land Department and Western Arizona Council of Governments.

The group has identified preliminary access management alternatives, and will proceed with the development of access management of the route based on information received during the open house.

"Sometime in the future a traffic interchange may be constructed at these locations," said WACOG Deputy Director Dave Barber, a committee member.

"This is a long-range plan that will not begin for several years."

Highway 93 is classified as a rural principal arterial highway and is an important route in ADOT's regional roadway system.

It serves as the primary commuter route between the metropolitan areas of Phoenix and Las Vegas.

The highway is also an important segment of the Canamex Corridor, a north-south route to improve the movement of goods, services and people as part of the North American Free Trade Agreement, Elters said.

The segment of highway included in the study traverses through lands owned by BLM, Lake Mead National Recreation Area, trust lands that are administered by the Arizona State Land Department and private lands.

Elters said the committee has been meeting with developers who plan to build along the route in an effort to anticipate future access needs.

The traffic volume on Highway 93 and its crossroads within the study corridor are expected to grow as the communities served by the route expand.

Evaluation of current and future access points along Highway 93 north of Kingman is necessary if high traffic volumes and highway speeds are to be maintained in future years, he said.

Access control is considered a key function in maintaining safety and the efficient flow of traffic along the corridor.

"The purpose of the study is to give us a tool to manage access on to this busy corridor," Elters said.

"We want to provide accesses to the highway without compromising the capacity of through traffic.

"We have learned that fewer access points produce better traffic flows."

Elters said that at some stage down the line a final access management plan may include frontage roads to provide further access.

"What ADOT does not desire are signals on this highway, and it is my understanding that the traveling public would not want that either," he said.

ADOT will continue to refine access management plans while following guidelines for access to a highway of this stature," Elters said.

DMJM+HARRIS project engineer Jennifer Bixby said the seven proposed traffic interchanges with crossroads that go over the highway are part of a "very long range plan.

"All funding is being applied to turning U.S.

93 into a four-lane highway first," Bixby said.

Another public meeting will be held in the summer to present the final recommended access management plan.
