There is significant concrete deterioration on this bridge, especially around the abutments and approaches. I observed some severe spalling as well as cracks in the concrete. Honestly I'm not surprised given how busy this bridge is, and given the fact that there tends to be a lot of traffic idling on the bridge waiting for traffic lights to change... but it does raise some concern about the long-term future of the structure. Interestingly, the Western Avenue Bridge which carries a near-equal amount of traffic is in much better condition.
