Been a long time since I've ridden the bridge. Advisability depends upon time of day and traffic volume. Definitely not a bridge to poke around on at a slow speed in the traffic lanes; do it, but be prepared to look for a break in the traffic and boogie. Not too bad really...you only have to crest the bridge and then you can really put the speed on to the end of the other side...25-30 mph. Keep your ears peaked for that 'gr-r-r-r-r-...whap-whap-whap-whap-whap-' sound, and get over far as you can if you hear it.
I would say plan on traveling at least 15mph, hopefully 20mph to cross, unless of course, you get a break in the traffic...then you can take a leisurely trip across it.
