Sidewalk/Greenway Feasibility Studies

Project Details

Feasibility studies bridge the gap between planning and design through a technical investigation whose outcome is constructable transportation projects, realistic costs, and actionable next steps towards funding. To be successful, feasibility studies must be based on engineering study and must consider physical and environmental constraints and opportunities as well as permitting and implementation challenges. At TPD, key staff work in all areas of project delivery, enabling our team to deliver achievable feasibility studies. We guide guided communities through the planning, funding, and construction of sidewalk and greenway projects, and we help clients come to consensus on solutions that balance the needs of competing factors. This project experience is instrumental in delivering designs that are ready for the next stages of engineering, permitting, and construction.


Saluda Grade Rail Trail
Inman, SC to Zirconia, NC

TPD is currently undertaking a feasibility study for the proposed 31-mile Saluda Grade Trail. The purpose of this project is to evaluate the feasibility of converting the former Saluda Grade rail line to a greenway, extending from Zirconia, NC to Inman, SC. TPD is leading several sub-consultants to develop the feasibility study and the Economic Impact analysis. In addition to the primary rail trail corridor study, TPD is also conducting complementary studies that will serve as a roadmap for connecting the future trail to the Ecusta Trail in Hendersonville, NC and to the Daniel Morgan System in Spartanburg, SC.

Delaware & Lehigh (D&L) National Heritage Corridor Planning & Design Services
Upper Merion Township, Montgomery County, PA

TPD was contracted for multiple projects between 2013 and 2017 to provide planning, engineering, and construction services for the 165-mile-long D&L Trail in Eastern PA. Stretching from Wilkes Barre to Philadelphia, the D&L trail also serves as the alignment for sections of the East Coast Greenway near Philadelphia.

East Coast Greenway Tinicum Heinz Connector Trail
Tinicum Township, Delaware County, PA

Tinicum Township commissioned TPD to assess and explore the feasibility of a new off-road route as an alternative to the existing segment of the East Coast Greenway, which runs along Industrial Hwy (State Road PA 291). The study aims to identify a preferred alternative route that eliminates the need for bicycle and pedestrian users to navigate difficult, high-speed, and high-traffic roadways without dedicated facilities.

Route 100 Multimodal Trail
West Whiteland Township, Chester County, PA

The Route 100 Multimodal Trail connects the Exton Train Station to the Chester Valley Trail, providing a safe pathway for both pedestrians and bicyclists. The project primarily involved constructing a 2,500-foot shared use path along the west side of Pottstown Pike (Route 100) from the Exton Train Station to the Chester Valley Trail at Commerce Drive, along with necessary modifications and installation of pedestrian components to existing traffic signals. A key part of this project included enhancing the Chester Valley Trail crossing of Route 100 at Commerce Drive. The new crosswalk consolidates pedestrian crossings, allowing individuals to safely navigate the bustling Route 100 using a single crosswalk rather than the three existing crossings.

Three Rivers Heritage Trail Feasibility Study
City of Pittsburgh, Allegheny County, PA

In collaboration with local partners, Friends of the Riverfront commissioned TPD to lead a community-driven feasibility study to identify a preferred route for a bicycle and pedestrian connection between Hazelwood Green and the historic Carrie Blast Furnace property. This multimodal facility will be an important link in the regional Three Rivers Heritage Trail and provide connections and improvements to the existing Duck Hollow Trail. The project will benefit both commuters and recreational users by providing a safe, seamless pathway through the Hazelwood neighborhood and facilitating access to nearby destinations such as parks and commercial centers. Through a combination of innovative in-person and online engagement activities and thorough analysis of this corridor, TPD has assisted in determining the most advantageous route option among the four possibilities, considering factors such as potential benefits, feasibility, and cost-effectiveness.
