SAN FRANCISCO (CBS SF) — San Francisco Mayor Ed Lee signed a $500 million transportation infrastructure bond for the November ballot on Monday while also unveiling other initiatives for improving pedestrian safety in the city.

The bond is intended to improve San Francisco’s transportation network without raising property taxes. It will be on the Nov. 4 ballot and will need a two-thirds majority vote by San Francisco voters to pass, according to the mayor’s office.

Investments planned for the $500 million bond include transit, accessibility, and maintenance upgrades, along with pedestrian safety enhancements, traffic signal replacements and improved bikeways.

Lee also unveiled the installation of new traffic signals at Sunset Boulevard and Yorba Street and announced that the San Francisco Municipal Transportation Agency has reduced the speed limit on Sunset Boulevard from 35 mph to 30 mph between Martin Luther King Jr. Drive and Lake Merced Boulevard.

Sunset Boulevard is part of the 6 percent of streets that account for more than 60 percent of the city’s severe and fatal traffic injuries, according to the mayor’s office.

An elderly man was struck and killed at Sunset Boulevard and Yorba Street in February and at least two other pedestrians have been struck and injured there this year. City officials announced in May the plans for the new traffic signals at the intersection.

“Our city needs to continue to support smart investments into our city’s aging transportation infrastructure to ensure safety and keep up with growth,” Supervisor Katy Tang said in a statement.
