"Now as we’re reopening, we’ve reached the point where we must resume parking enforcement so that we can clean our streets," Mayor London Breed said.

The bikeway improvements, which began in 2016 following two deadly hit-and-run collisions, will provide an uninterrupted protected bike lane between Market Street and Mission Bay.

The new westbound bike lane on Fell is intended to take pressure off the Panhandle's crowded mixed-use path.

Built in 1962, the bridge is set to come down as part of the project to speed up the 38 and 38R-Geary buses.

Starting this week, some streets will be closed to through vehicle traffic in order to prioritize walking and biking as well as to provide more space for social distancing.

Muni is slicing service to just 17 key lines as the shelter-in-place wears on.

"The decision to shutter the subways to promote social distancing has completely backfired," wrote one commuter.

Several bus lines are also being cut back as the agency loses $1 million a week from decreased ridership.

A possible bright spot for some local businesses in the Haight: some of the most disruptive work is underway while businesses are already closed by the shelter-in-place order.

Not everyone's gotten the memo on remaining six feet apart, so city agencies are intervening.

The city clarified a concern from many regular riders, noting that bike repair shops are considered as essential as auto repair shops.

"We need to be sure people can maintain six feet of space around them," said Jodie Medeiros of pedestrian organization Walk SF.

Tickets for street cleaning issued earlier today will be waived, but other driving restrictions — including meters — remain in place.
