Tonto Natural Bridge State Park Improvements

The Arizona Department of Transportation (ADOT) and Arizona State Parks (ASP) are planning improvements to the access road and parking areas at Tonto Natural Bridge State Park (TNBSP), north of Payson, Gila County, Arizona. The presently-planned improvements, which are being designed by AMEC, include the construction of a new parking area (the ramada parking area) and the widening of the existing office service road to accommodate an additional parking area (the office parking area). The planned parking area improvements will adversely affect a portion of archaeological site AZ O:11:38 (ASM) previously documented within the park boundaries as well as an archaeologically sensitive area that surrounds the site. ADOT requested that EcoPlan Associates, Inc. (EcoPlan) conduct concurrent geotechnical monitoring and Phase I data recovery followed by Phase II intensive Data Recovery as warranted within the park improvement areas in order to mitigate adverse affects the project may have.
