Status

In Design

Project Location

12th Street South between S Monroe Street and S Glebe Road in the Douglas Park neighborhood.

About Project

12th Street South is one of the Columbia Pike Bike Boulevards, which provides a low-stress east-west route for bicyclists parallel to Columbia Pike. The block of 12th Street South between S Glebe Road and S Monroe Street is currently a gap in street grid and requires bicyclists to divert onto a sidepath for one block. 12th Street South is identified as a constructed street connection in the Master Transportation Plan as well as the Columbia Pike Form-Based Code map.

Project Goals

Provide better connectivity parallel to Columbia Pike, with priority for bicyclists as part of the 12th Street South Bike Boulevard and the county’s low-stress bike network
Improve safety and accessibility along the street and at adjacent intersections
Connect S Lincoln Street to 12th Street South, per the Columbia Pike Form Based Code
Limit motor vehicle traffic volumes along 12th Street South in keeping with the bike boulevard

Key Design Features

Construct a new two-lane street with curb and gutter between S. Glebe Road and S Monroe Street
Install bicycle markings and signage to indicate bicycle priority along the street
Provide sidewalks on both sides of the street and high-visibility crosswalks at intersections
Sidewalk on north side, constructed by Pike 3400, will remain
Construct curb extensions and ADA-accessible pedestrian ramps at corners
Construct a traffic diverter at S Monroe Street that allows for east-west bicycle and pedestrian travel along 12th Street South but requires motor vehicles to turn onto S Monroe Street from either direction
Install street lights and landscaping

Winter/Spring 2019

Project staff presented preliminary concept designs at the Douglas Park Civic Association in February 2019.

Based on community feedback, the preliminary concept was revised to balance street network connectivity with concerns about increased traffic. The design concept was also updated to prioritize low-stress bicycle travel along 12th Street South and better align with its designation as a bike boulevard
