Trammell Bridge, Road bridge in Blountstown, United States

Trammell Bridge is a road bridge spanning the Apalachicola River between Blountstown and Bristol with separate lanes for each traffic direction. The structure allows river traffic to pass underneath while carrying State Road 20 across the water.

The original westbound span opened in 1938, built of steel and concrete piers by the Wisconsin Iron and Bridge Company; John D. Trammell, a Florida legislator from Calhoun County, introduced the bill to construct it. In 1989 the span was listed in A Guide to Florida's Historic Architecture. A separate concrete high-rise eastbound span opened in 1998 with funding secured by Robert D. Trammell, and from 2023 studies examined removing the old span and converting the newer one to two-way traffic.

The bridge carries the Trammell family name, honoring local figures who shaped the region's development. It serves as a daily crossing for residents moving between the two riverbanks.

Crossing is relatively straightforward for all vehicle types since it is part of an established state road. Travelers should note that the time zone changes depending on which direction they are heading.

What makes this bridge distinctive is that it crosses a time zone boundary, with its eastern end in the Eastern Time Zone and its western end in the Central Time Zone. This means travelers experience an hour difference simply by driving across.
