[SDCBC] SR56-Sorrento Valley Road connector

[Kathy Keehan]

Your input needed!

We've been asked to provide comments for a feasibility study for the
connection between the west end of the 56 bike path and Sorrento Valley
Road. As many of you know, there's a giant freeway in the way there, and the
City and Caltrans are looking for ways to get bicyclists across. 

There are a couple of options, basically one over the freeway and one under
it. Which do you like better? 

The bridge would be your typical 12 foot wide bike/ped bridge over the
freeway. It would be about 17 feet above the traffic at a minimum, and would
have 6.5% and 7.7% grades for the approaches (200 to 400 feet long depending
on the design), and 90 degree turns at each end of the bridge.

The undercrossing would go under I-5, with a minimum vertical clearance of 8
foot 3 inches. There will be concerns about water (particularly in wet
years), lighting, and security. The grades down to the undercrossing would
be about 7.5% for a couple hundred feet, then up at about 3% for about 80
feet. It will have a fairly sharp turn on the west side of the freeway to
connect to existing Sorrento Valley Road. 

Bridge - less potential maintenance, open even in wet weather, uphill both
ways, over noisy auto traffic/fumes

Undercrossing - downhill both ways, quieter, more potential maintenance,
potential to be closed in wet weather

Which do you prefer?
