[5] A draft root cause investigation identified the potential for fatigue and corrosion damage in the overhead suspension cables.

[6] The final root cause concluded in 1990 that the suspender cables had failed in fatigue at the top of the socket connector to the bridge deck.

The most cost-effective repair that would maintain the aesthetic appearance of the current structure was complete replacement of the suspender cables on a periodic basis (estimated at 20–25 years).

[7] A later study, completed in 2011, found that many components of the bridge were in good condition, with the notable exception of the original lead-based paint.

[8] The bridge was closed on weekends in the summer and fall of 2014 to remove the original lead-based paint and give it a fresh coat of international orange.
