Montgomery County, VA Mobility & Curb Rules: Bike Lane Rules (2026)

Montgomery County Code Section 10-32 sets street-design standards for the PUD-TND (Planned Unit Development-Traditional Neighborhood Development) zoning district, and one of them is a minimum bicycle-lane width. The ordinance requires that pedestrian and bicycle routes, lanes or paths connect all uses within the development to reduce reliance on motor vehicles, and requires street design generally to protect the safety of pedestrians and cyclists sharing the right-of-way. Where a separate bicycle lane is provided, distinct from a shared travel lane, the code sets its minimum width at four feet.

That standard sits alongside the district's broader street-design mandate that PUD-TND streets serve motor vehicle traffic, transit, pedestrians and bicyclists together, with room reserved for street trees, furniture and landscaping, and it applies on top of the grid-network and block-size rules the same section imposes on new TND street layouts. Because this is a zoning design standard, it is set and checked at the development-plan and site-plan stage, not through a separate bicycle-facilities permit; there is no county traffic-code rule in this file governing bike-lane obstruction or riding conduct outside a PUD-TND street network.
