ubject: Engineering Evaluation of Highway 115
Introduction
Highway 115 is an existing structure located within 200 feet of the proposed Hitch Rack Ranch Quarry
permit boundary. The location is shown on Figure 1. This engineering evaluation discusses the structure
location and components before evaluating potential impacts quarry development may have on the
structure and presenting how the quarry has been designed to minimize these impacts.
Structure Description
Highway 115 is located within 200 feet of the proposed Hitch Rack Ranch Quarry permit boundary at the
intersection with the proposed access road. This is at the easternmost extent of the permit area and located
away from mining areas. At this location, Highway 115 is a two-lane, paved road. The southbound lane
has an acceleration/passing lane that ends at the approximate location of the Hitch Rack Ranch Quarry's
proposed access road. Work activities in and along Highway 115 will only occur during construction of
the access road and acceleration and deceleration lanes.
Potential Impacts and Mitigation
Potential Problem: Construction of the access road could damage Highway 115.
Solution: Development of the quarry will require construction of acceleration and deceleration lanes on
both the north and southbound lanes of Highway 115. The road widening will result in improved lines of
sight at the intersection, which is also at the crest of a hill. All construction will occur within the Highway
115 right-of-way. The lanes will be designed following Colorado Department of Transportation (CDOT)
guidelines and regulations and will be permitted with CDOT.
Conclusions
Highway 115 is located within 200 feet of the proposed Hitch Rack Ranch Quarry permit boundary. The
road will be impacted by construction of acceleration and deceleration lanes, but all construction will be
permitted with CDOT, completed in cooperation with CDOT, and will occur within the Highway 115
right-of-way. There will be a temporary impact to Highway 115 while the acceleration and deceleration
lanes are constructed, and the impacts will be similar to other road widening construction projects. Once
