Alameda County, California Bridges: High Street Bridge across the Oakland Estuary
阿拉米達郡,加利福尼亞州橋梁:跨越奧克蘭河口的大街橋
Continuing south along the Oakland Estuary we arrived at the High Street Bridge (33C0026),
which is a diminutive version of the previously studied Park Street Bridge.
It has only two traffic lanes and carries less than 20,000 vehicles a day.
向南沿著奧克蘭河口,我們抵達大街橋,
這是以前學公園街大橋的一個小型版本。
它只有兩個車道,一天行駛不到兩萬輛車。
The High Street Bridge is 507 ft long, 24 ft wide, and provides 15.9 ft
vertical clearance above the deck. Like the Park Street Bridge,
it has counterweights in pits under the deck that help the rack and
pinion system raise and lower the two bascule leafs.
大街橋是507英呎長,24英呎寬,並在橋面上提供了15.9英呎垂直間隙。
像公園街大橋,它在橋面上幫助齒輪齒條系統升高和降低兩豎旋葉坑下的配重。
