Connecting Communities Through Transportation Options

Complete Streets Philosophy
While the term “Complete Streets” is relatively new this website is an effort to share information regarding the County’s current policies and practices. This site can be used as a guide for residents, business partners and regional government agencies of St Louis County to learn about the Complete Streets Philosophy.

Here in St Louis, it has been a long standing policy of the County to require development and redevelopment to include sidewalk/pedestrian paths in design plans. Furthermore, County engineers annually program, design and construct sidewalk “gap” projects to further improve pedestrian connectivity.

In 2013, County traffic engineers revised our “Bicycle Facilities Plan” and added some additional best practices to the policy. Subsequent to the Plan’s revisions, the County has added over 50 miles of on-street dedicated bicycle lanes as a feature to our bicycle network. The County continues to seek opportunities to expand the bicycle network and remains integrated with the efforts of Great Rivers Greenway, as well as other multi-modal partners to gain better understandings of the regional needs.

It is important that appropriate signing be in place along our roadway system to safely regulate, warn, and guide motorists, bicyclists, and pedestrians. Each sign serves a distinct function and shall only be used for that function in order to avoid the proliferation of signage. Examples of appropriate signage are pedestrian warning signs identifying a mid-block crosswalk or bike lane signage where there is an identified and appropriately marked bike lane.

In addition to standard signing, communities and businesses are often interested in wayfinding guide signs to direct tourists and other road users to key civic, cultural, recreational, shopping, and dining attractions. These signs, which must be placed off public right-of-way, can help vitalize a community and give a sense of place by including neighborhood iconography.

Pavement Markings

Pavement markings on roadways provide guidance and information for the road user and optimize roadway efficiency. The positive guidance of a roadway delineation system provides the visual information needed by the driver to correctly steer a vehicle through a variety of situations and conditions. Pavement markings are also used to define areas that are to be used by roadway users other than motorists, such as bicyclists and pedestrians, by delineating bicycle lanes and crosswalks. Pavement markings must be visible by day and night to inform and guide road users for safe travel.

Intersections are critical junctions because this is where two roadways come together and conflicts arise. Intersection design is highly context sensitive. Therefore, a good intersection design should consider what types of users will be entering the intersection. Essential items to consider are land use, neighborhood needs, traffic control type, safety, traffic flow progression, level of service, accessibility, radius design, and curb extensions/bulb outs.

Pedestrian scale lighting increases the length of time facilities can be utilized by pedestrians and bicyclists. It provides an inviting environment and an extra sense of security by increasing the visibility of pedestrians and bicyclists. Decorative light fixtures also provide an opportunity to include neighborhood branding and seasonal messaging, which further add character and a sense of community.

Lighting districts must be formed to provide for the installation, operation, and maintenance of this type of lighting. Further information regarding forming lighting districts may be obtained by contacting the County’s Department of Planning at 314-615-2520.

Any Individual or group of citizens interested in obtaining additional street lighting in their area may also contact Ameren of Missouri.
