Just outside Adirondack Park, the Alexandria Avenue Bridge spans the Lake George Outlet where the lake meets the LaChute River. Originally built in 1929, the deteriorating structure posed safety risks, threatened key utilities, and disrupted access for emergency vehicles and residents. A full replacement was critical to restore safe, reliable connectivity in this historic part of Ticonderoga.

Our infrastructure practice team was engaged to bring the new crossing to life. The reimagined bridge features four 70-foot NEXT beams topped with an asphalt overlay and flanked by vertical-faced concrete parapets, finished in a stone-textured treatment that complements the natural landscape.
Spanning a total width of 36 feet, the design accommodates two 11-foot travel lanes, 3-foot shoulders and a dedicated 5-foot sidewalk—providing secure, inclusive passage for both drivers and pedestrians. To further enhance connectivity, the pathway was extended past Alexandria Avenue to Lord Howe Street and Lake George Avenue, restoring a direct link to the LaChute River Walk Interpretive Trail.
The original bridge supported a 14-inch water main mounted along its exterior fascia; a functional but visually obtrusive solution. For the updated structure, the water main was discreetly integrated within the interior bay of the NEXT beams using a galvanized steel pipe sleeve and custom hanger assembly. During construction, we routed a temporary water line across the bed of the Lake George Outlet to uphold uninterrupted service.
Site work began shortly after the annual Ticonderoga Triathlon Festival to avoid disrupting the event. Backed by $2.8 million in federal funding, the resulting bridge represents more than a structural upgrade—it’s a vital investment in regional mobility, strengthening the backbone of a culture-rich Adirondack community.
