PennDOT District 6-0 Bridge Replacements
Bucks, Montgomery and Chester Counties, PA

This contract involved two work orders with rehabilitation of seven arch bridges under the On-Demand (WO6) Arch Bridge Rehabilitation, and the rehabilitation of the SR 0052 Bridge and SR 0322 Bridges in  WO5.  

The highlights from this group includes the following: 

 
 

Lenape Road Bridge

The existing Lenape Bridge is a seven arch stone bridge that was constructed in  the 20th century in the style of Pennsylvania’s nineteenth century stone bridges. It was built in 1911-1912 of random rubble construction and with conically shaped piers and a continuous parapet.  The Lenape Bridge was listed on the National Register in October of 1982 for its engineering significance, and is located over the floodplain to Brandywine Creek, with Brandywine Creek flowing just to the southwest beneath a separate bridge along S.R. 0052.  The bridge requires rehabilitation to strengthen and restore the mortar and repair and repoint the stone masonry.  For this project, Lotus conducted a Section 4(f) deminimis evaluation for the bridge, along with the following studies:

 

  • Prepared Scoping Field View (SFV) document
  • Level I CEE
  • Preliminary Jurisdictional Determination form
  • Plant and Aquatic Threatened & Endangered Species Habitat Assessments (including Phase I Bog Turtle)
  • Stream and wetland identification and delineations for preparation of Wetland Report
  • Completed Environmental Assessment form for PA DEP waterway permits
 

Lancaster Avenue Bridge

This portion of the project's objective was to rehabilitate the S.R. 0322 (Lancaster Avenue) bridge  over  the  East  Branch  of  Brandywine  Creek  in  the  Borough  of  Downingtown,  Chester County, PA.  The existing bridge is a four-span reinforced concrete closed spandrel arch built in 1921. The project scope is to rehabilitate the bridge by removing and replacing the sidewalks and balustrade railings, performing concrete repairs, replacing the earth fill with lightweight concrete fill and placing a new bituminous wearing surface.

Some of Lotus's responsibilities for this portion were:

  • Prepared Scoping Field View (SFV) document
  • Level I CEE
  • Wetland Delineations and CORPS of Engineers Jusrisdictional Determination
  • Threatened & Endangered Species Habitat Assessments (including Phase I Bog Turtle)
  • Completed Environmental Assessment form for PA DEP waterway permits
  • Section 4(f) Evaluation
 

Frankford Avenue Bridge

The Frankford Avenue Bridge was built in 1697, and listed on the National Register of Historic Places in June 1988 for its engineering and transportation significance. The Frankford Avenue Bridge, also known as the Pennypack Bridge, the Holmesburg Bridge, and the King's Highway Bridge is thought to be the oldest surviving roadway bridge still carrying a modern highway in the United States. The three-span, 73 foot-long twin stone arch bridge carries Frankford Avenue (S.R. 0013) over Pennypack Creek in Pennypack Park. The bridge arches are original and are well buttressed with rubble stone piers.
The bridge substructure requires the reconstruction of spandrel walls and wingwalls, stone masonry repair and repointing throughout.  

In addition to project scoping, we were responsible for completing the following studies for this bridge:

  • Threatened & Endangered Species Coordination/Clearance
  • Delineations of wetlands and waters
  • CEE preparation and permitting
  • Section 4(f) Evaluation
