61936 | Structure Hardening Group 2025

This intent of this project is to repair scour holes and remediate scour issues at 4 structures. The structures and associated issues are:
1. Quakertown Road over Cooks Creek in Springfield Township, Bucks County (BRKEY 6938; BMS# 09-0212-0140-0000). The bridge substructure is in poor condition due to scour along the far abutment and far left wing wall. The footing of the far abutment is exposed for the full length and has lateral undermining up to 1'.
2. US 202 over Little Valley Creek in Tredyffrin Township, Chester County (BRKEY 10144; BMS# 15-0202-0360-0931). The proposed repairs aim to address severe scour and undermining present. Specifically, there is a 10'x6' scour hole in the upstream channel and a 6' deep x 100' long scour hole located downstream. Additionally, undermining of the apron is estimated to be up to 4.8' and in-filled.
3. US 202 over Branch of Trout Creek in Tredyffrin Township, Chester County (BRKEY 10156; BMS# 15-0202-0424-2315). This structure is in fair condition, but has a poor channel rating. Repairs are planned for heavy spalling on the culvert sides, undermining, and scour. The concrete apron on the downstream side of the culvert is exposed up to 6" with minor undermining at the upstream end. The channel has a scour hole that is approximately 4' deep and has allowed for undermining of the upstream apron.
4. Susquehanna Road over Tributary to Wissahickon Creek in Upper Dublin Township, Montgomery County (BRKEY 27613; BMS 46-2017-0160-0773). The culvert is in fair condition and the channel rating is poor. The downstream end of the culvert is fully exposed at the oulet with undermining up to 3.5'. Scour is present downstream with multiple holes at the apron. The scour holes vary in size and are up to 2' deep.
Resilience improvements include:
1) rehabilitation of an existing eligible surface transportation facility,
2) installing riprap
3) adding scour protection at bridges, and
4) adding scour, stream stability, coastal and other hydraulic countermeasures
