Clinton-Frankfort Road Bridge Emergency Project

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.

MSA Thruway Tunnel

Owner:  Cranberry Township & PennDot
Value:  2.8 Million
Completion:  Fall 2020
Scope of Project:  Golden Triangle will be the subcontractor of Allegheny Excavating and will install a Precast Concrete Arch System beneath SR228.  This 150’ long tunnel will connect the I-79 ramp with Cranberry Springs Drive and reduce traffic congestion on SR228.  Before construction of the tunnel, Golden Triangle will build a temporary shoring wall for the excavation of the tunnel.  In addition to the tunnel, Golden Triangle will pour curb, islands, and also pave the concrete on both sides of the tunnel.  Sidewalks and bike lane will also be installed to make the area more pedestrian friendly.

I-79 Bridges over North Boundary RD

Owner: Pennsylvania Department of Transportation
Value:  14.6 Million
Completion: Spring 2021
Scope of Project:  Replacement of deficient bridges on I-79 over North Boundary Road in Cranberry Township.  The new structures will also increase the maximum clearance height of North Boundary Road.  Prior to demolishing the existing bridges, a temporary bridge must be erected between the two existing bridges to maintain traffic on I-79.  In addition to the bridges being replaced, pavements on either side of the bridges will be reconstructed/ resurfaced and widened, new drainage will be installed, and guiderail will be replaced.  North Boundary Road under the bridges will also be resurfaced and the sidewalk will be replaced.

Kenmawr Bridge over NS RR

Owner: Pennsylvania Department of Transportation
Value: 12.5 million
Completion: Fall 2021

Scope of Project: Replacement of the structurally deficient and functionally obsolete Kenmawr Rd Bridge over the mainline tracks of the Norfolk Southern Railroad.  The new structure will be raised to provide the necessary vertical clearance required for NS Railroad to run double-stacked trains beneath, as well as lengthened to include a second span to accommodate future expansion of the Port Authority’s East Busway.  Prior to demolishing and replacing the existing structure however, a temporary bridge structure with sidewalk will be constructed to the west of the existing structure so as to maintain traffic through this busy corridor while the new bridge is being replaced.  In addition to the bridge itself, the approach pavements, drainage, sanitary sewer, water line, curb ramps, guiderail, traffic signals, etc will also be replaced as part of this project.

PA turnpike Southern Beltway – 55C1-1 Section

Steel girder erectionfor the 55C1-1 section of the PA turnpike Southern Beltway. The dual, 4-span structures consist of 72 individual steel sections which are field spliced to create the 1015’ continuous composite bridges over SR 50 and Millers Run Road. Golden Triangle is the structures subcontractor for Beaver Excavating on this section.


SR576 Section 54ABC Cashless Tolling

Owner: Pennsylvania Turnpike Commission
Value: 5.2 million
Completion: 2018
Scope of Project: The construction of the first cashless tolling system on the Pennsylvania Turnpike Commission roadway system.  Project scope included the construction of a service building with architectural treatment, drilled caisson foundations, installation of precast concrete columns with architectural treatment and the installation of steel gantry structures.  Work also included roadway reconstruction, drainage improvements, sign installation, precast white barrier and guide rail installation along with the application of pavement markings.

SR576 Section C1-1

Project:  SR576 Section C1-1
Owner:  Pennsylvania Turnpike Commission
Value:  39 Million
Completion:  2019
Scope of Project:  As a subcontractor, Golden Triangle is constructing dual mainline bridges approximately 1,000 LF in length each, a connector bridge from SR50 that is over 800 LF and a dual span overpass bridge as part of the new Turnpike construction between SR22 and SR79

SR30 Emergency Slide Remediation

Project:   SR30 Emergency Slide Remediation East Pittsburgh        
Owner:  Pennsylvania Department of Transportation        
Value:  6.5 Million
Completion:  2018
Scope of Project:  For the reconstruction of SR30 which included construction of a 400 LF solider pile retaining wall with tiebacks, 35,000 CY of excavation, 30,000 CY of rock embankment, 15,000 of soil embankment, and reconstruction of the roadway.   The schedule required working 7 days per week, 24 hours per day.

Bentleyville Interchange

Project:  Bentleyville Interchange
Owner:  Pennsylvania Department of Transportation
Value:  67 Million
Completion:  2018
Scope of Project:  The complete reconstruction of the Bentleyville Interchange on SR70 which included construction of 2 bridge structures, extensions of 2 box culverts, and construction of a soundwall.

SR70/79 Interchange South Junction

Project:  SR70/79 Interchange South Junction
Owner:  Pennsylvania Department of Transportation
Value:  35 Million
Completion:  2015
Scope of Project:     As part of the reconstruction of the south junction a 1,140’ flyover bridge was constructed, 2 2-span bridges, a redesigned culvert for the 79 Southbound Ramp, and several small box culvert extensions were constructed.
