| 摘要： | The 21st Avenue undercrossing bridge, which carries Route 99 traffic over 21st Avenue in Sacramento Calif., is a notable example of the benefits that precast concrete and accelerated bridge construction (ABC) bring to a community. The original bridge, built in 1958, consisted of two single-span cast-in-place reinforced concrete cored slab bridges on strutted abutments, which were later linked by a cast-in-place prestressed cored slab. The bridge deck was showing severe signs of distress in the form of heavy pitting, abrasion, cracks, and spalls, indicating it had to be replaced. However, the high volume of traffic on Route 99 meant the project design had to be completed quickly and with as little disruption as possible. |
