The service concept itself — routes, stops and how it would run.

Current — In force. This is the version to rely on. The adopted final version.

This document is mostly tables, forms and figures rather than prose, so it does not divide into sections. The text is below in the order it appears; the original is linked at the foot of the page, and we will provide it in another format on request.

Richmond Parkway 35% Plans

Key Improvement Types

The following treatments are detailed in the 35% plan set and

will be critical for project success on the corridor.

Separated bike lanes will be elevated to the

sidewalk level to physically separate bicyclists from

motor vehicle traffic, enhance bicyclist comfort

and safety, and provide new landscaping and/

or bioretention opportunities in the buffer.

Raised driveways at private intersections will

provide a continuous, flat surface for pedestrians and

cyclists. Where driveways are within the public right-

of-way or where future driveways are developed,

signs and design features will alert drivers that

they are crossing a pedestrian/bike facility.

Bioretention facilities may be installed in the

roadway buffers or landscaping. The next design

phase will determine appropriate treatments.

Protected intersections are designed to keep

bicyclists fully separate from vehicles until the

intersection, enhancing visibility and safety by reducing

right-turning vehicle speeds and giving bicyclists a head

start in crossing the street. These will be combined

with protected right-turn signal phasing for vehicles

to enhance safety for cyclists and pedestrians by

separating them in time from conflicting vehicle traffic.

Bus boarding islands separate waiting riders from

the separated bike lane, which is routed behind

the island to reduce bike/pedestrian conflicts.
