Bridges are structures built to allow vehicular and pedestrian traffic to cross an obstacle such as a body of water, valley, or railway. Since the first bridges were built thousands of years ago, many types of bridges, both large and small, have been built worldwide. Here are four of the longest bridges in North America.
1. Lake Pontchartrain Causeway
Located in southeastern Louisiana, this bridge spans Lake Pontchartrain and is one of the longest bridges over water in the world. This feat of engineering Vancouver BC opened in 1956 and has been carrying vehicles across the water ever since.
2. Chesapeake Bay Bridge-Tunnel
Not to be confused with the Chesapeake Bay Bridge in neighbouring Maryland, the Chesapeake Bay Bridge-Tunnel is located in Virginia and spans nearly 18 miles. This bridge, which was completed in 1964, replaced the ships and ferries used to shuttle people and goods across the Chesapeake Bay for hundreds of years. In addition to the bridge portion, there are two underwater tunnels on this structure that stretch for one mile each.
3. Confederation Bridge
Confederation Bridge connects the provinces of New Brunswick and Prince Edward Island. The newest bridge on this list, Confederation Bridge opened in 1997 and is the longest bridge in Canada. In addition to vehicle traffic, there are shuttles that can transport pedestrians and cyclists between the two provinces.
4. Seven Mile Bridge
Seven Mile Bridge is located in the scenic Florida Keys and connects the Middle Keys to the Lower Keys. There is an older Seven Mile Bridge open to pedestrians and cyclists only, and the newer one that runs parallel and is open to vehicular traffic. The newer bridge opened in 1982 and has been featured in several televisions series and films since then.
If you get the chance, cross one of these four bridges in North America.
