The project includes the bridge rehabilitation of Route 23 bridge (Marietta Avenue) over Route 30 in East Hempfield Township, Lancaster County. The purpose of this project is to provide a continued safe and efficient crossing on Route 23 over Route 30.

Within the project area, Route 23 is a two-lane roadway located in a predominately open urban setting on rolling terrain and is classified as a Urban Minor Arterials. The land use surrounding the roadway is predominantly open grass areas with residential properties farther from the bridge. The Route 23 within the project limits has a posted speed limit of 35 miles per hour and an average daily traffic volume of approximately 9,900 vehicles per day. 

The existing structure was built in 1966 and was reconstructed in 2004.  The structure is a four-span prestressed concrete I-Beam bridge supported on concrete abutments and multi-column pier bents. The structure length is 213 feet and has a curb-to-curb width of 32 feet.

The project involves superstructure rehabilitation activities including strip seal gland replacements. Substructure rehabilitation including concrete encasement of the existing pier caps, general concrete patching and slope wall repairs at the existing abutments. The horizontal and vertical geometries will not be changed. 

Route 23 will not be detoured during construction. Construction is anticipated to be accomplished using staged temporary traffic control for both Route 23 and Route 30. 

The project is currently in design, and construction is expected to take approximately 4 months at this site.  The exact construction timeline is not currently known, but construction is currently anticipated to begin in the Fall of 2026 or Spring of 2027.

The purpose of the plans display is to introduce the project and solicit public input, questions, or concerns regarding the project.​
