Two major street projects are nearing completion in Joplin and Webb City.
The Connecticut Avenue/KCS grade separation project that has redirected traffic south of 20th Street on Connecticut for going on a year is expected to be complete by October. The new Stadium Drive in Webb City, essentially a north bypass around Webb City High School, is also scheduled for completion this fall.
Connecticut Avenue
The City of Joplin retained Allgeier Martin and Associates Inc. and Design Nine - a railroad specialists company from St. Louis - to design a grade separation of Connecticut Avenue between 24th and 26th Streets and the Kansas City Southern railroad.
"The most efficient option long-term was to take Connecticut Avenue underneath the railroad, thereby avoiding the maintenance and replacement of a road bridge with only a 50-year life span," said Mike Walker, vice president with Allgeier Martin. "Raising the railroad approximately 16 feet and lowering Connecticut about seven feet accomplished this project."
Allgeier Martin provided the stormwater design of the project to help reduce flooding upstream of the railroad, which had been an issue for the city in the past. The cost of the project was $4.6 million and was paid for with a special sales tax approved by Joplin voters.
Allgeier Martin was also hired by The Empire District Electric Co. to design the relocation plans and conduct all surveying and staking for the line relocation, as well as to obtain easements for the new transmission and distribution power line alignment and to oversee the construction of the relocation. According to Walker, this portion of the project was completed in March 1009 and included the relocation of approximately 1.7 miles of power lines. The new line encompassed 104 new wood poles, 12 new steel poles, 2791 feet of transmission line, 21788 feet of distribution line, 878 feet of secondary, three railroad crossings, and multiple road crossings.
Stadium Drive
Tri-State Engineering was the engineering firm hired by the City of Webb City to design a north bypass to safely route traffic north of residential areas. According to Gabe Lett, communications director with Tri-State Engineering, the new street will also improve traffic flow and safety in and around three Webb City Schools.
"Particularly during Friday night football games and school beginning and ending hours," he said. "This new roadway is in Phase 2 completion, which involves paving and completing the tie-in intersections at Madison Avenue, Pennsylvania Avenue and Aylor and Main Streets."
The projects has been financed by the transportation sales tax, municipal bonds and through Environmental Protection Agency funds associated with the superfund cleanup. The first phase of construction cost approximately $650,000, while the second phase was close to $700,000.
Stadium Drive will route from Madison Street on the western limits of the project to Main Street on the east. Also, Pennsylvania Street will be extended northward to intersect this new road. Lett said new roadway width will vary between two and three lanes, with a total roadway length of 2,700 linear feet along Stadium Drive and 600 linear feet along Pennsylvania.
Snyder Construction served as general contractor for phase one while Newman Brothers Construction was general contractor for phase two.
