There are no bike lanes in Arnold, Missouri.
In 2022, the City of Arnold published a Bicycle and Pedestrian Master Plan. In this document, a few Shared Use Paths were proposed as theoretical long-term goals, as well as cooperation with the Great Rivers Greenway and the Mississippi River Trail. However, apart from sidewalks on Jeffco Blvd, nothing of substance has come of this plan to date.
Notably, this plan does not propose or even discuss bike lanes on either Jeffco Blvd or Telegraph Rd. This plan does not seem to address bicycle access to retail districts. Instead, it is focused on connecting parks/recreation, schools, and residential districts. There is nothing wrong with those goals, but it tends to put cycling into a box for recreation and ... kid commuting?
