The Polk Street redesign and Muni Forward improvements for the 30-Stockton are the big-ticket items on the Streetsblog calendar this week:

• Wednesday: The SFMTA is holding an open house about transit improvements for the 30-Stockton in North Beach, where you can weigh in on transit-only lanes, bus stop changes, and other proposals to speed up the route. 6 p.m.
• Friday: Speak up for a safer Polk Street at SFMTA’s public hearing on the street’s redesign. Bike lanes (protected and unprotected), bulb-outs, and other changes are all in play. You can speak at the hearing or email comments to sustainable.streets@sfmta.com. 10 a.m.
