Route 136 Safety Improvement Project
Nottingham & Fallowfield Townships, Washington County, PA
The Route 136 Safety Improvement Project (S.R. 0136, Section 136) is located in the Village of Ginger Hill. The project area is primarily comprised of a mix of residential, commercial and mining properties. This section of Route 136 has experienced a high volume of crashes due over the past decade. The primary factors leading to the high crash volumes include poor horizontal and vertical geometry, inadequate sight distance, high travel speeds and poorly controlled access to the highway.
As a result, PennDOT Engineering District 12-0 prepared the S.R. 0136 Ginger Hill Engineering Study (dated July 2008) which identified various substandard conditions and also reviewed various alternatives to improve both the horizontal and vertical geometry. In addition, other low cost safety related recommendations were proposed to help improve safety along the corridor. As part of this process, public meetings were held in an effort to get public input on the proposed alternatives and to develop a recommended alternative. Based on these meetings and an engineering review of the proposed alternatives, PennDOT District 12-0 developed a recommended alternative (Alternative 1) which would be advanced into Preliminary Engineering. Alternative 1 involves the relocation of Ginger Hill Road (S.R. 1087), Pittsburgh Road (S.R. 0917) and also Cracker Jack Road (S.R. 1067) to help improve sight lines at these locations and the upgrade of S.R. 0136 to meet current 3R criteria.
TPD was selected by PennDOT Engineering District 12-0 in the fall of 2011 to begin work on Preliminary Engineering and Final Design Activities. TPD reviewed and refined the preferred alternative selected by PennDOT District 12-0. This included modifying shoulder widths and re-aligning Route 136 near the intersection with Route 917. The refinements were as a result of coordination with public officials and the local property owners and based on efforts to minimize right-of- way and utility impacts. TPD prepared Construction Plans, Traffic Control Plans, Signing and Pavement Marking Plans, Cross Sections, Erosion and Sediment Pollution Control Plans, Post Construction Stormwater Management Plans and Right- of-Way Plans. TPD was also responsible for coordination with local review agencies, affected utility companies, the school district and local emergency services personnel with respect to the permits and construction staging.
Through coordination with the District and property owners, the overall property impacts were reduced from 12 properties to three (3) properties. This allowed the overall right-of-way acquisition time and cost to be significantly reduced.
