Design Activities
Summer/Fall 2025
Final design is currently underway for the interchange and environmental studies continue to advance in support of the environmental permitting process. Fieldwork is also underway to inform the design team of key features as they make every effort to minimize impacts to the community and the environment.
In the coming weeks, you may come across field crews conducting:
- Utility Investigations - Subsurface utilities are being located along John Fries Highway (PA 663).
- Geotechnical Testing - Drilling is planned along the shoulders of I-476 and the interchange ramps. Work is scheduled to begin in the Fall 2025 (weather permitting). All work will be performed at night from Mondays through Thursdays.
- Wetland Investigations – Additional fieldwork is planned to begin in Summer 2025 and continue through the Fall. Work will be performed along both sides of the Turnpike between Molasses Creek Bridge and Steinsburg Road Bridge.
