The replacement of the functionally obsolete Mission Road bridge over Rock Creek had been a priority for the City of Fairway, Kansas since the flood of 1998. The cost of the project had kept it only as a priority until the FHWA introduced the SATETEA-LU fund in 2005. Senator Pat Roberts helped secure 1 million dollars from the program to help fund the project.
Through the efforts of the City of Fairway, Shafer, Kline & Warren, Inc., Johnson Cunty Public Works, Senator Pat Roberts and Pyramid Contractors, Inc., the new Mission Road bridge was reopened in December 2008. The bridge was completed on schedule with an opening ceremony held December 10, 2008.
The project removed four homes from the 100-year floodplain, and has allowed for safe travel on a major road during a 1% storm. Besides the brige the project inlcuded roadway grading and pavement, sidewalks, storm and sanitary sewer relocations, utility relocations, creek channel expansion and grading, erosion control measures and vegetation restoration of native grasses, wildflowers and shade trees.
Pyramid Contractors, Inc. a heavy contractor and member of the Associated General Contractors of America since 1994, recognized early in the bid process the unique opportunity this project offered. Pyramid specializes in constructing haunch slab bridges and takes priding in building structures which exceed standard function by enhancing and beautifying the neighborhoods. Years of experience in designing and constructing the falsework for haunched slab bridges was a valuable asset for this project.
The curved alignment and variable width roadway presented unique challenges. By designing their own falsework plans, Pyramid was able to maintain constant communication between the field and the office allowing them to make adjustments and maintain production. In addition to the bridge, Pyramid removed the existing structure, performed excavation and site grading, installed the storm sewer system and the articulating block concrete erosion control and managed subcontractors for the other aspects of the project.
2009 Public Works Project of the Year
for Transportation - $5 to $25 Million.
The widening of 159th Street involved the improvements from the existing two lane to a four-lane divided roadway from Antioch to Metcalf. Included in this project were new storm sewers, turn lanes, curb and gutter, street lighting, raised median, sidewalks and bridges over U.S. 69 Highway.
Construction of the interchange with access to U.S. 69 Highway was not included in this project. However, this project was designed for future construction of the ramps when funding becomes available.
Pyramid completed this project in August 2012 and was named as the recipient of the Concrete Promotional Group 2012 Excellence in Concrete Awards - Bridge.

A $13.6 million contract was awarded in May 2012 to Pyramid to replace deteriorated sections of a wall that supports Route 169's northbound lanes; fix bridges that support the southbound lanes; repair guard rail and barrier; and replace drainage between the northbound and southbound lanes, which will resolve the highway's problems for the long term.
Nearly 60 years ago, northbound Route 169 along the east bank of the Missouri River was a city road to the Downtown Airport. However, a solid road built on a levee made of dirt and sand presented challenges. The loose material must be kept in place so that the pavement remains solid and does not break apart.
A "bin wall" 12 feet high in some places was built to keep the underlying base in place and support the road. The bin wall is made up of corrugated steel panels. MoDOT took over this road in 1994, and in the last decade, those steel panels had rusted out enough that replacement is now necessary.
The removal and replacement of about a mile of bin wall holding up the east side of the northbound lanes, the repair and rehabilitation of the southbound lanes, and drainage improvements were performed in an unusually restricted area that has an active rail yard on the east and the Missouri River on the west.
Construction was completed 10/31/2012 several weeks ahead of the scehduled 12/16/2012 deadline.
