Bay-Bridge-- Experts-urge-quick-action-to-protect-

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Lessons can be learned from problems of the new Self Anchored Suspension
Bay Bridge.


The new problems here as discussed in the  story below are:
1. The main cable is not currently protected properly against corrosion and
is suspect to corrosion and fracture of wires.

2. The suspender cables are not in vertical plane like most other
suspension bridges . In this bridge suspenders cross the bridge decks to be
connected to the mail cables. As a result inspectors who need to inspect
suspenders will work above the  traffic.

3. The post-tensioned concrete segmental part of the bridge has had it
tendons left in the conduit without grout for months while rain water had
filled the conduits. According to experts in the story below the tendons
cannot be inspected now for corrosion or fracture of wires.
