Lindbergh Boulevard and New Halls Ferry Pedestrian Improvements
This ARRA funded project included the development of final design plans for pedestrian facilities along five miles of urban arterial roadway. The improvements included two routes in St. Louis County for MoDOT’s St. Louis Metro District: Route 67 (Lindbergh Blvd.) and Route AC (New Halls Ferry Road). The first order of work for HR Green was to complete a comprehensive accessibility audit of each corridor by walking each route. The goal of the accessibility audit was to determine where pedestrian facilities were lacking, where existing pedestrian facilities did not comply with current ADA requirements, and to determine the Pedestrian Access Route (PAR) for each road.
The accessibility audit included an evaluation of the following items:
- Existing Sidewalks – Did existing sidewalks have adequate width, cross slope and running slope?
- Gaps – Were there gaps in existing sidewalk routes?
- Connections – Were there potential connections to be made with other sidewalks?
- Curb Ramps – Were curb ramps installed properly? Were cross slopes and running slopes below ADA minimums? Were detectable warnings ADA compliant?
- Existing Intersections – Were crosswalks and detectable warnings present and ADA compliant?
- Raised Channelizing Islands – Were curb ramps or cut-throughs present and ADA compliant?
- Existing signalized intersections – Were proper pedestrian signal indications and pushbutton detectors installed? Were pushbutton detectors located properly with regard to accessibility and ADA compliance?
After the accessibility audit was completed, and based upon the identified PAR, HR Green began the preparation of preliminary and final design plans. Plans for all new pedestrian improvements were made in accordance with the Public Rights-of-Way Accessibility Guidelines (PROWAG). Final design plans were completed based upon a maximum construction budget of $2M. Because the project was funded with American Recovery and Reinvestment Act (ARRA) funds, the project development schedule required prompt completion of the final design plans. For this reason, HR Green completed all work within a 90 day timeframe. This included establishment of field control, aerial photography, mapping, and preparation of all contact documents.
