The Federal Highway Administration, Central Federal Lands Highway Division (FHWA-CFLHD), in cooperation with Arizona Department of Transportation (ADOT) and Tonto National Forest (TNF), is proposing improvements to a 11.16-mile, gravel section of the Apache Trail (Arizona State Route [SR] 88) between milepost (MP) 229.2 near the Apache Lake Marina and MP 240.6 near the Theodore Roosevelt Dam. The project is within Maricopa County, located approximately 30 miles northwest of Globe, Arizona.
The proposed improvements include applying an aggregate base and a chip seal pavement to an 11.16-mile section of the roadway. Improvements to sight distance in five spot locations would be completed to improve roadway safety. In addition, the project would replace, repair, and/or extend culverts that are not currently functional or have been damaged by flood events within the project area.
Purpose and Need
The purpose of the project is to improve the resiliency of the road corridor to reduce maintenance demands and improve and maintain accessibility while protecting elements of the historic road, as practicable.
The project is needed because routine maintenance requiring the continual importing of material and regrading of the road surface contributes to watershed damage, places the roadway at further risk to unintentional damage, and requires extensive financial resources. Undersized culverts can’t handle flows during heavy rain events resulting in road washouts that lead to further degradation to the watershed and limit public access.
Finding of No Significant Impact (FONSI) and Final Individual 4(f) Evaluation.
