What is the Mt. Tabor Road Restoration and Pedestrian Safety Project?
The Mt. Tabor project includes just over a half mile of new road construction, roadway stabilization improvements, full curbs, gutters, and sidewalks to help improve the neighborhood. The need for this project is clear, considering the renewed surface cracking and foundation shifting occurring near the Slate Run creek slopes, along with the lack of any pedestrian facilities along the roadway. This project will provide a much needed reconstructed road that will aim to stabilize and provide a long-term solution to the road-erosion issues, as well as improve pedestrian safety and provide traffic calming mechanisms.
“The Mt. Tabor Road Project is another example of our focus on investing in neighborhoods and improving the infrastructure of our city,” stated Mayor Jeff Gahan. “This project will stabilize the roadway along a failing creek hillside, improve drainage, and bring sidewalks which connect residents to local schools, parks, and neighbors.”
Road Slide and Erosion issues along Mt. Tabor Road:
In 2013, a slide occurred on the hillside of Mt. Tabor Road. The City provided a temporary solution to the road failure and erosion issues at that time, and this new federally funded project (80% federal funding, 20% local funding) will ensure that a long-term solution is in place that keeps residents and families in the neighborhood safe. The total anticipated cost for this segment of the Mt. Tabor road reconstruction project is about $3.1 million, with the city’s 20% totaling about $620,000.
The city is utilizing drilled shafts to help stabilize the roadway. A drilled shaft system is constructed by drilling a borehole, placing reinforced steel into the drilled shaft, and then filling the remainder with concrete. This system helps form a strong retaining wall that will resist further movement of the roadway and hill.

We know that construction projects are a hassle for neighbors, and that’s why we are doing everything we can to get this project done quickly and efficiently. Recently, construction engineers came to us with a way that we can shave two (2) full months of construction time off of the project, but in order to get this done, we have to close part of Mt. Tabor Road to thru traffic.
While construction projects like this are never fun, we believe that the stabilization of the roadway and safety of all those who travel and live on it is of paramount importance and must be repaired. We are hopeful that this project can be fully completed by late Summer / early Fall 2019.
