Holmes Mill Road Over Miry Run: A County Bridge Done Right
Not every bridge replacement is a megaproject. Some of the most important ones happen on the roads people drive every day without a second thought. Monmouth County Bridge U-38 on Holmes Mill Road over Miry Run in Upper Freehold Township had reached the end of its useful life. The original steel girder floor beam system with reinforced concrete box beam widening was both structurally deficient and functionally obsolete. The bridge was among several Monmouth County structures identified through the NJDOT Local Bridges, Future Needs program, which directs state grant funding to counties based on total deck area and the amount of deck area in poor condition. Monmouth County, responsible for maintaining 980 bridges across its jurisdiction, prioritized this crossing for full reconstruction.
Our team provided comprehensive engineering services for the complete removal and replacement of the structure. The existing bridge was replaced with a three-sided precast concrete structure that improves hydraulic performance, increases structural capacity, and simplifies long-term maintenance for the County’s Division of Bridges.
Designed to Last, Detailed to Belong
Functionality alone doesn’t make a good bridge. Holmes Mill Road runs through the rural landscape of Upper Freehold Township, where a stark concrete box would feel out of place. Our professionals designed a concrete form-liner with the appearance of rubble stone on all exposed concrete surfaces, giving the new structure a visual character that fits the agricultural and wooded surroundings rather than announcing itself as a piece of highway infrastructure.
The project also required sensitivity to what was beneath the surface and in the historical record. Our team developed an archaeological monitoring plan that was submitted to and approved by the Historic Preservation Office before construction could proceed, ensuring that ground disturbance during demolition and reconstruction was properly documented and managed. It’s the kind of detail that adds complexity to a county bridge project but reflects the level of care that a community like Upper Freehold expects and that a crossing over Miry Run deserves.
