logoSPELLMAN AVENUE – PHASE 1   GENERAL INFORMATION SHEET
August 8, 2013

 

Introduction

The Spellman Avenue Corridor is a well-traveled north/south roadway in Crestwood, carrying traffic from several residential subdivisions southerly to Rayburn Avenue and northerly to Big Bend Road.  The present configuration of the roadway is a two-Spellm top pictlane roadway with 11′ lanes.  A few short segments of sidewalk exist on the west side of the roadway in isolated locations, but there is no continuity along the traveled way.  The pavement is in poor shape and failing in many areas due to poor subsurface conditions, poor drainage, and the effects of wear and tear over time.

 

Proposed Improvements

This project will widen the driving surface to include 27-feet of new asphalt pavement with concrete curb and gutter on each side of the road.  For comparison sake, the current pavement thickness is about 4-6 inches thick, with minimal rock underneath the pavement.  New asphalt pavement depth will be almost double the thickness (7.5-inches thick) over 4-inches of rock under the pavement.  This pavement section is better capable of handling the heavy loads that vehicles such as trash trucks deliver to it.  In addition, a five-foot wide sidewalk will also be added to the west side of the road along the entire length of the project, to connect Rayburn with Spellman Park.  Proposed improvements for the second phase of the project (Ponderosa, Acorn, Oak Ridge, and Holmes to Big Bend) will include the same widening, pavement, and pedestrian accommodations as this phase.

 

Cleaner Water

To address the requirements of the Metropolitan St. Louis Sewer District (MSD), wet ponds and pervious pavement (sidewalks for the length of the project and the parking lot of Spellman Park) are being used to meet the water quality needs of the project.  Pervious sidewalks allow stormwater runoff from rain events to soak into the sidewalk and therefore into the ground.  By soaking directly into the ground, harmful Spellman I Gen Info Pictsubstances such as grease, oils, salts, and other “dirty” particles are removed before they enter downstream creeks and rivers, making the water naturally cleaner and healthier for fish and other inhabitants.  Additionally, a wet pond performing a similar function of treating the water, is being incorporated within the existing green spaces of Spellman Park.

 

Schedule

The project is currently “out for bid” with bid opening scheduled for September 5th.  Preliminary construction work should start in late 2013, with the final project completed in late 2014.
