This project provides for the design and construction of a new eight-to ten-foot wide sidepath for 3.3 miles along Bowie Mill Road from Olney Laytonsville Road (MD 108) to Muncaster Mill Road (MD 115) and continues along Muncaster Mill Road to Needwood Road. The project also provides a new pedestrian bridge over Rock Creek North Branch for continuation of the sidepath along Bowie Mill Road.

Design started in FY23 and will be completed in FY26. Land acquisition will be completed in FY27 and utility relocation and construction will be completed in FY29.

The Montgomery County Bicycle Master Plan, approved in November 2018, recommends a sidepath along Bowie Mill Road. The project is a critical connection in the existing bicycle network between the existing trails and important destinations including Needwood Road Bike Path, North Branch Trail, the Inter-County Connector (ICC) Trail, Shady Grove Metro Station, Sequoyah Elementary School, Colonel Zadok Magruder High School, and Olney Town Center.

State aid totals $9.9 million. $1.5 million was approved in the FY22 Maryland General Assembly. $2.1 million was approved in each of the FY23, FY24, and FY25 General Assembly sessions. An additional $2.1 million of State aid is preauthorized by the General Assembly for FY26.

A pedestrian impact analysis has been completed for this project. The County Executive asserts that this project conforms to the requirement of relevant local plans, as required by the Maryland Economic Growth, Resource Protection and Planning Act.
