Layton Bridge Projects
There are two projects upcoming for the Layton Bridge that carries Layton Road (State Route 4038) over the Youghiogheny River and River Trail in Perry Township, Fayette County. The first project is a preservation project on the bridge and tunnel. The second project includes the proposed replacement of the Layton Bridge as well as work on the single-span, single-lane bridge carrying Layton Road over Washington Run, and the associated roadway connecting these two structures. Both bridges were originally designed and utilized by a railroad.
As the Layton Bridge is on the National Register of Historic Places (NRHP), we must adhere to Section 106 of the National Historic Preservation Act.
Preservation Project 2022
While the larger project continues through design, to allow the structure to continue to safely carry traffic for the immediate future, a separate project is scheduled for the Summer of 2022.
This Preservation project includes the Layton Bridge and Layton Tunnel. The proposed scope of work consists of repairing masonry elements at both portals of the tunnel, installing additional riser beams on the bridge floor system as needed, mitigating deficiencies to the bridge timber sidewalk, repairing, or replacing bridge joints as needed, and performing any miscellaneous concrete and/or steel repairs to the bridge deck, superstructure, and substructure as needed.
The closure of the bridge for repairs began on July 5, 2022 and is anticipated to remain in place through late August 2022. Work is scheduled to be completed in the fall of 2022.
Project Update 8-26-22
PennDOT District 12 would like to inform motorists that the Layton Tunnel and Bridge which carries Layton Road (Route 4038) over the Youghiogheny River in Perry Township, Fayette County is scheduled to reopen Monday, August 29.
Substructural work will continue from under the bridge through October. This work may require short-term flagging operations with alternating traffic.
Work is being performed by Allison Park Contractors, Inc. as part of a preservation project on the Layton Tunnel and Bridge.
Replacement Project 2025
This project has substantially completed the Section 106 Historic Structure process in the Preliminary Engineering phase. To that end, the project team has completed efforts and submitted the Historic Bridge Rehabilitation Analysis (HBRA) and the Alternatives Analysis.
The preferred alternative recommended in the Alternatives Analysis, and being carried forward into the Preliminary Engineering Phase, involves the replacement of the existing Layton Bridge with a new bridge just to the east of the existing bridge. This will allow the existing bridge to remain open during construction.
The Preliminary Engineering Phase of the project commenced in May of 2021. Detailed survey and mapping of the project corridor was completed in the Fall of 2021. With the completion of the survey, conceptual alignments are now being evaluated in advance of setting the Line, Grade & Typical Section of the roadway. We plan to finish Preliminary Engineering in 2023 followed by Final Design and Right-Of-Way acquisition. Funding is programmed to begin construction in late 2025.
