Study: Stockton Hill Road stretch carries more vehicles per day than I-40

Stockton Hill Road from Interstate 40 north to Airway Avenue still carries more vehicles each day than does I-40 through Kingman.

The numbers are from the 2003 update of the 1997 Kingman Area Transportation Study, and most of the growth projections engineers made in the 1997 study is on track.

Stockton Hill Road now carries 31,500 vehicles per day compared with 26,200 in 1997.

Engineers projected the traffic count would be 31,800 by 2004 and 34,800 by 2005.

I-40 carried 22,800 vehicles per day past the Stockton Hill Road interchange in 1997, and the projection for 2005 is 27,075 vehicles.

The 2003 count already shows 27,205 vehicles on I-40 at the Stockton Hill Road interchange.

The Kingman Police Department accident reports indicate 201 accidents in the vicinity of the traffic signal on Stockton Hill Road and the entrance to the Albertson/Wal-Mart shopping center in the 1999 to 2002 period.

The emergency entrance to the Kingman Regional medical Center is at the same traffic signal.

Despite the heavy traffic at the signal, at least one driver doesn't mind the wait.

"I go to the aisles near the traffic signal at Albertson's and use the light all the time," Jackie Zoephal said.

"You may have to wait to get in or out at the signal, but that is the best way."

The I-40 numbers show about 15,000 vehicles per day along stretches of the interstate east and west of Kingman.

The additional traffic within Kingman is city drivers and those who enter the freeway from U.S.

Highway 93, coming from Bullhead City or Las Vegas.


93 connects with I-40 at the Beale Street interchange in west Kingman.

There actually are more vehicles, 19,561, leaving I-40 at the Beale Street interchange going north on U.S.

93 than the 15,000 that continue west on I-40

The increase in traffic was expected to be greater than the 26,000 vehicles going north on U.S.

93 by 2003.

"There are no real surprises," Kingman Community Development Director Dennis Roberts said.

"The 1997 KATS report said extra lanes would be needed to carry the Stockton Hill Road traffic close to I-40"

He said city officials instead have looked for ways to take traffic off or slow the increase on the busiest streets such Stockton Hill Road.

Studies in other cities have shown extra lanes may not help, Roberts added.

He said expanding Stockton Hill Road to six lanes from I-40 to Airway Avenue would be the most expensive street project ever attempted in Kingman at a time when dollars are not available to do other needed street improvements.

The number of vehicles traveling Route 66 (Andy Devine Avenue) has increased to nearly 20,000 from I-40 south to Harrison Street and Louise Avenue.

"I wonder why commercial development has not grown along Andy?" Roberts said.

Further south along Andy Devine Avenue, more than 12,000 vehicles travel through historic downtown Kingman daily.

Hualapai Mountain Road traffic has increased faster than estimated in 1997, from 5,000 per day from Andy Devine Avenue east to Eastern Street to 8,294 during 2003.

Engineers estimated that 8,300 trips per day would not occur until 2005.

Traffic along Louise Avenue from Route 66 east to Eastern Street has increased about as projected, with 7,635 vehicles per day counted in 2003 compared to 4,900 in 1997.

Some 8,100 vehicles per day was the projection for 2000.

Construction in the East Golden Gate Improvement District may have reduced the count, Roberts said.

The projected increase in traffic along Louise Avenue east of Eastern Street has not occurred.

The count in 1997 was 1,800 vehicles per day, and for 2003 it was 1,912, instead of a projected 4,000 per day.

It appears most of the increase along Louise Avenue has come from developments to the north along both sides of I-40 including houses as far away as Vista Bella.

Louise Avenue was the route into Kingman along U.S.

93 before the construction of I-40, Roberts said.

It joined U.S.

Route 66 at the tracks with much commercial and industrial development to the north.

Lewis Kingman Park along Route 66 was a highway rest stop built by the Arizona Department of Transportation prior to I-40.

ADOT deeded the rest stop to the city.

Roberts said the traffic counts are part of the updated KATS study contracted by the city, ADOT and Mohave County.

The data and recommendations will guide Kingman City Council decisions for street construction during the next 20 years.
