Although the highway was designed and built to what were, at the time, high standards, with a 100-foot (30 m) wide right-of-way in most places, it was accident-prone because it lacked a median barrier. One segment of the so-called "Bloody Bayshore" was "Boneyard Hill", a steep grade through the Visitacion Valley near the San Francisco city line, running past a bone meal plant. Causes of the crashes included turning conflicts at intersections, and speeding drivers crossing the centerline to use the oncoming lanes as a passing lane. The roadway was entirely at-grade except for crossings of rail lines. It generally followed the present alignment of the Bayshore Freeway, but deviated in several places: Old Bayshore Highway in San Jose, Veterans Boulevard in Redwood City, Bayshore Highway in Burlingame, a destroyed section of road through San Francisco International Airport, and Airport and Bayshore Boulevards from South San Francisco through Brisbane into San Francisco. Within that city, the new highway continued three miles (5 km) along the present Bay Shore Boulevard to Army (Cesar Chavez) Street and Potrero Avenue.
