The Roosevelt Bridge is a major highway segmental bridge across the St. Lucie River in Stuart, Florida. Carrying U.S. Route 1, it was built to supersede the old Roosevelt Bridge, which had twin parallel drawbridges, one for northbound traffic and the other for southbound. The new bridge, completed in 1996, is raised and much longer than the older twin drawbridges. The southbound span of the old bridge is still functional for road and boat traffic and now carries two-way road traffic for what is now known as Dixie Highway, County Road 707. The new high-level Roosevelt Bridge is approximately one mile long and is made of two three-lane sections running parallel to each other. The northbound bridge was completed first, and housed two lanes of both north and south-bound traffic until the second bridge was finished. Because of high traffic volume and visibility, the Roosevelt Bridge is a frequent location for many protests and political campaigning in the area.

U.S. Highway 136 (US 136) is a short U.S. Highway in Keokuk, Iowa. The route was designated nationally in 1951 and has remained largely unchanged through Keokuk since then. The highway originally crossed the Mississippi on the Keokuk Rail Bridge, which was the second bridge built and operated by Andrew Carnegie's Keokuk & Hamilton Bridge Company in that location. While it was designed for wagons and early automobiles, crossing the rail bridge became difficult in larger modern vehicles, specifically semi trucks. As a result, a new automobile-only bridge was built directly to the south of the older span. The Keokuk–Hamilton Bridge opened in 1985 eight months early and under budget.
