Cherry Hill Road Bridge – Middlefield, Connecticut The New England Chapter of the American Concrete Institute, Inc. and The New England Ready Mixed Concrete Associations honored Nathan L. Jacobson & Associates, Inc. with an award in 2001 for their design of the Cherry Hill Road Bridge project in Middlefield, Connecticut.

Mary Griswold Steube Fishway – Old Lyme, Connecticut Completed in 1998, the Mary Griswold Steube Fishway at Lower Mill Pond Dam in Old Lyme, Connecticut was constructed as a cooperative venture of the Connecticut River Watershed Council and the Old Lyme Conservation Trust. Named in honor of a generous benefactor of the Old Lyme Conservation Trust who donated the project site, the fishway provides a means for anadromonous fish (alewives) to pass the dam and spawn in the pond and central reaches of the Mill River. The fishway consists of concrete entrance and exit structures, a concrete resting pool with a side viewing window for counting fish transiting the fishway, and an aluminum steep pass structure. Aesthetics were an important part of the project as the fishway could be seen from a dwelling located immediately across the Mill River from the project. Nathan L. Jacobson & Associates, Inc. received a…

Quinnipiac University Law School – Hamden, Connecticut The 130,000 square foot School of Law, located at the base of Sleeping Giant State Park, forms the western terminus of the University’s “Village Street”.

Depot Road Bridge – Coventry, Connecticut The Portland Cement Association honored the Depot Road Bridge with an Award of Excellence, in an international competition recognizing creativity and imagination in the aesthetic design of concrete bridges. Completed in 1996, the Depot Road Bridge project included the replacement of an historic stone arch bridge built in the early 1800’s. The new bridge consists of a precast rigid frame, with cast-in-place concrete parapets and wingwalls, supported on timber piles for scour protection. Most notable is the concrete form-lining and color-staining utilized on the wingwalls and parapets to simulate the appearance of stone masonry. Consideration of site aesthetics during design of roadside safety improvements also led to the selection of an AASHTO approved steel-backed timber guide rail that complements the appearance of the simulated stone masonry. Nathan L. Jacobson & Associates, Inc. was reported to be the first to use either of these two…
