Street Design Manual

3.2.4 B - Avenue 4-Lane and 6-Lane, Divided This cross-section features four or six general travel lanes, bike lanes, and buffered sidewalks on both sides of the street. Due to the emphasis on through vehicle mobility, it is not conducive to on-street parking; however, the outside general travel and bike lane could be reconfigured to be a transit / bike / right-turn only lane if warranted by context and placed within the multimodal transportation network. Four- and Six-lane Divided are conducive to use of GSI practices including street trees in grated wells, curbside bioretention and/or bioretention in curb extensions/bump-outs, and bioretention in medians. Permeable pavement may be desirable within on-street parking areas and for sidewalks.
