Clinton-Frankfort Road Bridge Emergency Project

SR 3082 A10 Location Map (002).png

Project Overview

On September 9th, 2022, a truck collided with the wingwall of the single-lane stone arch bridge carrying SR 3082 (Clinton-Frankfort Road) over Potato Garden Run in Independence Township, Beaver County. This collision caused the masonry wingwall to collapse and caused damage to the headwall over the arch. Upon inspection, it was determined that the road needed to be closed and that the bridge would need to be replaced.  

PennDOT obtained approval for emergency procurement, and the emergency contract with Golden Triangle Construction/Mackin Engineering has been executed to immediately begin design efforts and mobilize to remove the existing bridge. 

$2,970,000 in federal funding has been obtained for the replacement of this critical link. The federal funds are a direct result of the additional funds made available in Federal Fiscal Year (FFY) 2022 and 2023 from the Bi-Partisan Infrastructure Law and will not impact any regionally funded projects.    

The Clinton-Frankfort Road Bridge is classified as a minor collector and has an average daily traffic (ADT) volume of 1,519 vehicles per day. The replacement bridge will be 30 feet wide to carry two 11-foot wide lanes and 4-foot wide shoulders on each side. The proposed structure will be a rigid frame structure, which is made up of vertical abutment walls and a top slab, and riding surface. The alignment of the road will be changed slightly to improve the sight distance approaching the bridge. Molds and dye will be used to design the wingwalls to look like stone. In addition, the stream crossing will be brought up to current safety standards. The existing roadway is posted for a 10-ton weight limit, and this posting will not change once the bridge is replaced. In an effort to improve safety along the entire length of Clinton-Frankfort Road, larger weight limit signs and additional directional signs will be added to redirect trucks away from the Clinton-Frankfort Road bridge.

Project Updates

1-3-23

Work began this week at the project site with the contractor (Golden Triangle) mobilizing and cutting down the majority of the trees needed for demolition to begin on the existing bridge and construction of the new bridge.

Construction of the upstream access road is anticipated to start this week as well depending on weather conditions and demolition of the existing structure is anticipated to start on January 16, 2023.  

The majority of the stones from the old bridge will be carefully removed and delivered to Raccoon Creek State Park for reuse at the park.  

Other miscellaneous activities to prepare for the bridge demolition will continue this week including the installation of erosion and sedimentation control devices (e.g. filter sock, etc.).

Environmental Information

Overview

As part of the environmental process with all federally funded projects, we are obligated to adhere to regulations pertaining to the National Environmental Policy Act (NEPA).  Under the broad umbrella of NEPA, we are required to examine and avoid, minimize, or mitigate potentially adverse impacts to the social and natural environment when considering approval of proposed transportation projects.  For the SR 3082 project, the main area of environmental studies included historic resources and assessment of stream impacts.  Section 106 of the National Historic Preservation Act of 1966 (NHPA) requires federal agencies to take into account the effects of their undertakings on historic properties.  The regulations require the federal agency to consult with the State Historic Preservation Officer (SHPO). In Pennsylvania, the SHPO is located in the State Historic Preservation Office at the Pennsylvania Historical and Museum Commission (PHMC).  We have completed this coordination as well as stream and wetland assessments.  Additional information relating to the 106 coordination and waterway permit is included below.

Above Ground Cultural Resources

The bridge carrying SR 3082 (Clinton Frankfort Road) over Potato Garden Run was twice determined not eligible for listing on the National Register of Historic Places (NRHP).  The bridge was first evaluated as not eligible for listing in the NRHP in 1998 as part of the Pennsylvania Statewide Historic Bridge Survey.  The bridge was re-evaluated in 2022 through a joint effort by PennDOT and Pennsylvania Historical and Museum Commission (PHMC) to evaluate all stone arch bridges in the Commonwealth.  Due to loss of integrity, the bridge was again determined not eligible for listing on the NRHP.  No other above ground cultural resources were identified within the project Area of Potential Effect (APE).  It should be noted that although the bridge is not historic, PennDOT has coordinated with the Department of Community and Natural Resources (DCNR) and they have agreed to accept the stones that were used in the existing bridge structure for use at nearby Raccoon Creek State Park.  Golden Triangle Construction plans to demolish the bridge in a manner that minimizes impact to the stones so that the majority of them can be used for various restoration projects in  the park.

Archaeological Resources

Following an initial field view completed on September 19, 2022, the District 11-0 Cultural Resource Professional (CRP) archaeologist determined that the southwest and southeast quadrants upstream of the existing bridge required a Phase I archaeological survey to assess for the presence of unrecorded archaeological resources. On October 4, 2022, a Phase I archaeological survey was completed for the project in the southwest and southeast quadrants and involved the excavation of five shovel test pits (STPs) encompassing a testable area of 0.19 acres. Each STP was excavated by hand at least six inches into B-horizon subsoils and no artifacts or features pre-dating the early twentieth century were identified. Based on the results of the archaeological survey, the project as designed will not affect significant archaeological resources and no further investigations are warranted.

Waterway Permit

Ongoing coordination is occurring with the Department of Environmental Protection (DEP) and other environmental agencies on the project's required permitting.  A permit pre-application meeting with the project team members and environmental agencies occurred on November 17, 2022, to discuss the project scope and impacts to environmental resources.  PennDOT has recently obtained a General Permit (GP-8 and GP-11) for the removal of the existing structure.  Work to remove the structure under the approved general permits is anticipated to start on 12/22/22.  We are currently applying for a small projects joint permit application for a Water Obstruction and Encroachment Permit to construct a new bridge.  As part of the joint permit application process for construction of a new bridge, there is a public comment period which affords interested parties the ability to provide written comments on the proposed project.  The 30-day comment period will commence upon publication of the application in the PA Bulletin. We anticipate submitting the joint permit application in the near future and the public comment period will begin shortly thereafter. Individuals objecting to or in favor of the issuance of a Water Obstruction and Encroachment Permit must submit any comments, suggestions or objections within 30 days of the date of the PA Bulletin notice. Comments should contain the name, address, and telephone number of the person commenting, identification of the application to which the comments or objections are addressed, and a concise statement of comments, objections, or suggestions including the relevant facts upon which they are based.  When available in the PA Bulletin, comments should be sent to the following email address: RA-EPWW-SWRO@pa.gov
