The SF Department of Public works produced these before and after digital visualizations of Second Street's preferred design which is currently making it's way through the CEQUA process. The design features raised and protected cycle tracks, similar to the type used widely in Copenhagen. This sort of first rate cycling improvement is justified because Second Street is a critical part of the City's cycle route network, connecting downtown to the Giant's Stadium, Central Waterfront, and Blue Green Way. Besides raising property values this will be much safer for pedestrians and cyclists. It's been in process for over 10 years, and is scheduled to be completed in 2016.
