Yes, I saw the bike bridge today that did not exist when I was in
graduate school in the late 1970's. I'm not sure that I would call the
bridge a "reasonable alternative", since it requires two left turns
from/to University Ave.
Regardless, the bike bridge treats bicyclists as something other than
drivers. Although I presented a paper in 1974 where I introduced the
idea of "bicycle bottlenecks" (what Dan Smith subsequently and more
accurately called "barriers to bicycle travel") and the need to resolve
them, sometimes with paths or bridges, it bothers me when the
interchange of a conventional street like University Ave is considered a
barrier to bicycle travel, since the difficulty only arises if a
bicyclist is not considered a driver and there is a desire to get
bicyclists out of the way of motor vehicles.

I've never bicycled over the University overpass, but I drive there fairly
frequently, since I'm a hard-core folkie and the best folk music venue in
the US (with the possible exception of the east coast) is in Berkeley on
Addison...Freight & Salvage Coffee House.
As a fairly hard-core vehicular cyclist, who regularly rides comfortably in
heavy traffic, I'd have to say that I'd be intimidated by riding westbound
University on the overpass (and I'm sure I'll get screamed at by Dan G for
being an Uncle Tom, or some such).
The overpass is fairly old...looks like something built in the 1940s, and
the lanes are very narrow. It crosses both the mainline RR tracks (4
tracks) and I-80. I'd have no problem using the bridge eastbound, where
one lane handles the northbound I-80 offramp, and the other southbound I-80
traffic and waterfront traffic. Though the bridge carries high-speed
traffic, going eastbound a bicyclist is at the top of the bridge and can go
fast when the lane from northbound I-80 joins.
It's westbound which I'd find intimidating, since this is a de facto
freeway onramp with two narrow and very high-speed lanes...and involves
climbing a moderately steep gradient.
I-80 is on the west side of the wide RR ROW, and both westbound lanes of
the bridge first climb over the tracks, then at the top of the overpass the
right lane has the opportunity to make a right onto northbound I-80, then a
short bit later a right onto the cloverleaf loop to southbound I-80.
Traffic on the bridge goes very fast, and the lanes are very narrow with no
shoulders whatsoever. The vast majority of the drivers are going
northbound or southbound on I-80 and have a freeway speed mentality.
While I don't like the principle of the bicycle prohibition, this is one
case where I'd be very happy to take the new multi-million dollar bridge to
get to the shoreline.

I'm sorry, but I don't understand several points in your message:
What do you mean by "dealt with positively"?
What do you mean by "more bike friendly circulation plans"?
What do you mean by "jousting at each windmill separately"? By "overall
plan", do you mean seeking solutions at the statewide or national level
such as the change in highway design standards that I am working toward?

Certainly "selling" alternates is better than bogusness, but "selling" can be problematic too.
The "selling" of bike lanes, with mere labels on signs and pavement, creates an expectation that that is where bicyclists belong (and not anywhere else), sometimes even having that effect on roads without bike lanes.
A similar expectation can be created by signs indicating alternate routes for cyclists. For example, a sign that says "BIKE ROUTE" and an arrow to the right could easily imply to many that bicyclists going straight are doing something wrong, just like that "bike route"/"use sidewalk" combo I posted yesterday implies to many that bicyclists on the road are doing something wrong.
There is precedent for creating these kinds of expectations with "truck route" signs. For example, this one in Carmel is used to indicate that trucks are supposed to turn right on 3rd Ave, implying they are not supposed to continue straight on Junipero St.:
I haven't had a chance to read this thread but I"m glad people are
discussing it.
Certainly the issue has been a longstanding one, and ther have been
efforts to challenge the prohibition here as well as in the Solano
tunnel. An interesting legal issue, besides the right to ban
bicycling, arises as the signs at the tunnel prohibit use on the
"roadway," which presumably excludes the gutter area which is wide
enough for some bicyclists to use. Proposals of placing a 'bicyclist
in tunnel' light have been floated in the past (Berkeley bike/ped
planning has been understaffed, sometimes without staff, over the
past decade).
We did spend 9 years correcting the problems witth the overpass by
creating the signature bridge to the Marina, touching down in Aquatic
park. Yes it is inconvenient, as one can travel a good bit out of the
way, in part due to ADA grade requirements. But it is a huge
improvement. As with most access issues, there is a need for the
strong transportation cyclist to be accommodated along with safe and
comfortable access for all nonmotorized travelers. Opening the
overpass is still needed (although Richmond Bridge access is a much
higher priority, along with Bay Bridge access, were one needing to
choose).
