Engineering a Stronger Community: Improving efficiency of a vital St. Louis link while reducing highway noise on existing neighborhoods

The New I-64 project included the rebuilding and upgrading of all pavement, bridges and interchanges between Spoede Road in St. Louis County and Kingshighway Blvd. in St. Louis City. A new directional interchange with I-170 was also part of the reconstruction.

Civil Design, Inc. provided roadway, retaining wall, and soundwall design assistance to Parsons for the central portion of the corridor between McKnight Road and Bellevue Avenue. CDI engineers worked at Parsons headquarters to increase efficiency and create a seamless design team environment. CDI also assisted with post-design services throughout the construction phase. These services included addressing issues arising during construction and reviewing shop drawings for the retaining walls and soundwalls.

Engineering a Stronger Community: Removing unsightly erosion and improving downstream water quality

Civil Design, Inc. was part of the design team for the new MetroLink Interlocking at the University of Missouri-St. Louis campus, completing the analysis and design for an erosion problem along the east side of the tracks. CDI designed approximately 500 feet of the 6’ x 4’ box culvert to replace the existing ditch. CDI completed the USACE 404 permit for this project, which was determined to be a USACE Jurisdictional waterway. CDI also provided site design for the new signal house and a high-rail access road for maintenance vehicles.

Engineering a Stronger Community: Saving lives and reducing crashes on I-44 by removing ponding water from shoulders and lanes

This section of I-44 was widened in 1995 from four lanes to six by eliminating the grass median and replacing it with the two additional lanes and shoulders. As a result, the profile for this section of highway is very flat with long segments at zero percent grade, resulting in pooling of water and causing hazardous road conditions.
CDI provided an evaluation of the drainage issues along this section of median and developed a set of alternatives for its reconstruction. The new shoulders drain toward existing inlet locations, which have been reconstructed at lower elevations. Final plans and cost estimates were developed for several alternative methods of reconstructing the shoulders to provide for improved drainage.

Engineering a Stronger Community: Providing a more efficient transportation link in one of Missouri’s fastest growing counties

This project upgrades the section of the Page Extension between Mid Rivers Mall Drive and Kisker Road to freeway standards. The design required an accelerated schedule in order to maintain the federal funding. CDI was added to the design team because of our ability to work seamlessly with other companies in a collaborative manner. CDI provided assistance with bridge and wall survey submittals, and traffic control plans for this project.

Engineering a Stronger Community: Renewing and enhancing the entrance to one of St. Louis’ most cherished neighborhoods

Broadway Avenue at the entrance to Soulard was in bad condition with heaving medians and multiple utility patches causing the road to drain and ride poorly. Along with Park Avenue and 7th Street, this portion of Broadway was to be milled and repaved with new traffic signals and intersection improvements as a significant part of the design of this project. CDI provided surveying, hydraulic design and traffic control plans to the Crawford, Bunte, Brammeier team.
