The Arizona Department of Transportation (ADOT) has announced the completion of a new westbound Interstate 10 climbing lane in the city of Benson, aiming to alleviate traffic woes and improve travel safety along a notably hectic section of highway frequented by many large commercial vehicles. On this project, which rings in at a cost of $2.1 million, Arizona Department of Transportation has extended a third lane on I-10 westbound. This extension spans slightly over half a mile between the junctions with state routes 80 and 90, connecting with the pre-existing climbing lane that originated just east of State Route 90 and stretches for 1.6 miles. The additional lane, placed between mileposts 303.56, and 302.95 is designed to reduce the hindrance of slower-moving traffic on uphill stretches and provide a means for vehicles to overtake with greater ease.

Furthermore, the initiative included the sealing of existing pavement, improved lighting measures, fresh pavement markings, upgraded signage, and the resurfacing of the westbound on-ramp for SR 80. Work commenced at the top of the year in January, signaling Arizona Department of Transportation's commitment to timely infrastructure enhancement.

In-depth information regarding the project's specifics can be found on Arizona Department of Transportation's website, where interested parties are encouraged to visit azdot.gov/projects and navigate to the "Southcentral" section to locate the "I-10: SR 90 to SR 80 Climbing Lane Extension Project" webpage for further reading on this roadwork completion.
