The project consists of the demolition and replacement of 554 bridges that stretch across the entire state of Missouri. Every county in the state has at least one bridge replacement and some counties get more than twenty. The bridges are mostly located in rural areas, crossing small streams and rivers. Some bridges cross other roadways or railroads. The average new bridge will be 28' wide and 128' long. The work has a contracted completion date of October 31, 2014, which averages 135 bridges completed per year. However, the KTU project team has put together an aggressive schedule to complete construction by December 31, 2012.
Through December 15 2009:
Environmental: All 554 sites have been visited and evaluated for sensitive environmental issues. There are 131 project sites identified that may require ACOE 404 permits based on several criteria. Four 404 permits have been acquired and 38 sites have been cleared of 404 permitting. There are also five historic bridges and two archeological sites that affect scheduling and constructability.
Geotechnical: Drilling and geotechnical investigations have been completed at 280 project sites.
Surveying: Topographic and site survey has been completed at 275 project sites.
Design (Preliminary): Preliminary Design has been completed on 103 bridges. At this stage of the process preliminary hydraulic requirements are established and topographic survey is laid over the bridge that was scoped during the estimated process.
Constructability Review: KTU has conducted 107 constructability reviews with the design subcontractors. During this review the length and number of spans are adjusted to accommodate site, utility, and stream sections.
Type, Size, and Location (TSL) Drawings: Seventy TSL drawings have been completed and 24 of these are pending MODOT approval. The TSL drawing provides enough information to order precast components, order steel piling and enough detail to conduct a bid letting.
Release for Construction (RFC) Drawings: Four RFC drawings have been completed.
Complete Construction: Four bridges have been completed (12/15/09).
