Considering the Baker-Barry Tunnel not just a passage, but a crucial thread in a military tapestry is key. This tunnel, also locally known as the Bunker Road Tunnel, connects what were once the isolated Fort Barry and Fort Baker. Imagine these forts, geographically close yet separated by daunting terrain. Before the Baker-Barry Tunnel, travel between them was arduous.
In 1911, a post commander lamented the perilous land route. He described a “crude and treacherous” road. The road lacked protection from steep falls. It was so narrow that wagon teams couldn’t pass. Some slopes had a seventy-five percent grade. A fall could mean a 400-foot drop. The War Department allocated funds for fencing at the most dangerous spots. A separate school was established at Fort Barry due to these dangers.
Then came the vision for the Baker-Barry Tunnel. In 1916, plans solidified. The U.S. Army began construction in 1917. The tunnel was completed in 1918. Its purpose was clear. It would furnish a direct highway. It eliminated difficult grades and exposure to hostile fire. The tunnel held strategic value in war and peace. It eased cargo landing troubles at Fort Barry.
The Baker-Barry Tunnel has undergone several transformations. Rebuilt in 1925 to replace rotting timbers, it saw its width increased in 1937. Surveys in the 1960s revealed cracks in the concrete lining. The tunnel closed in 1989 due to safety hazards. A rebuild was completed in 1994 and the tunnel reopened in 1995. Repairs occurred again in 2017.
The restricted clearance inside the Baker-Barry Tunnel reflects its military origins. It was built for military vehicles. Today, it accommodates a single highway lane and cycle lanes. Traffic lights control motor vehicles at each end. The tunnel suffered increasing water ingress. Locals called it the “car wash.” This put users’ safety at risk. A repair plan was put forward to seal leaks, upgrade lighting, and replace utilities.
The Baker-Barry Tunnel’s design is also noteworthy. It lies beneath the U.S. 101 highway. The tunnel is cut through serpentine rock. Originally, it featured a timber structure. A macadam road with cobblestone gutters completed it. The timber was even reused from a grandstand.
Today, the Baker-Barry Tunnel continues to serve. Automotive traffic is controlled by traffic lights. This allows one-way traffic for five minutes at a time. The single reversible lane is flanked by bicycle lanes. The five-minute wait is sometimes called “the longest stoplight in America.” So, as you pass through the Baker-Barry Tunnel, remember its story. It is a story of military necessity. It is a story of engineering challenges, and a vital link between two historic forts.
