Proposed concept

This project concept will utilize the opportunity of a full-scale reconstruction of 6th Street to provide a parking protected bike lane from 4th Street to Virginia Street. This project will utilize existing excess capacity and transition from four lanes to two lanes with turn pockets at key intersections.

This project will enhance safety throughout the corridor for pedestrians and bicyclists by reducing pedestrian crossing distances by over 20 feet at each intersection along the corridor. Additionally, a raised median with or without landscaping may provide additional safety benefits along the corridor. If desired, this or other traffic calming design elements may be added as the project design is refined. The project will also enhance transit by creating floating bus stops which allow buses to stop in the travel lane for more efficient boarding and re-entering the flow of traffic. This project will reconstruct the intersection with Wells Avenue to remove the existing high-speed slip lanes and provide protection for bicyclists and pedestrians as they wait to cross. This project includes potential consideration of mini-roundabouts at Sutro Street, Evans Avenue, and Valley Road. (This project concept has been refined to include a center turn lane throughout the length of the corridor.)

SUMMARY

4th St. to Virginia St.

Curb-Protected Bike Lane

Sutro St., Valley Rd., and Evans Ave.

Optional Roundabouts

Included Conceptual Intersection Enhancements

1 Protected Intersection
2 Sets of Protected Corners
Conflict Markings
Floating Bus Stops
Two-Stage Turn Boxes

BENEFITS

Safer and more comfortable ride for cyclists
Better intersection alignment
Improved visibility and accessibility for pedestrians
Reduced cross distances for pedestrians
Bus stop improvements

CONSIDERATIONS

VEHICLE CAPACITY:

Loss of travel lanes between Virginia and 4th (one in each direction)

PARKING:

Potential increase with new parking on south side (100 on-street spaces): (48 spaces) between 4th and Sutro / (52 spaces) between Sutro and Wells

Possible loss where curb extensions occur (18 spaces)

OTHER:

Lane narrowing where possible along corridor
