Blanchette Bridge Rehabilitation

The eastbound I-70 bridge over the Missouri River in St. Charles was opened in 1978 and was in need of improvements when KCI was awarded the rehabilitation project in 2020. The majority of the work was to be completed in two phases over an aggressive 9 month schedule, and included expansion joint replacement, steel structure repairs, barrier wall enhancements, sealing the bridge deck and full structure repainting.

I-44 Meramec River Bridges

Due to increasing traffic volumes in the area and the deterioration of the 1950’s era construction, in 2018 KCI was awarded the project to replace two bridges over the Meramec River near Fenton, MO.  This project includes new bridges over the river, replacement of the EB and WB Watson Road bridges, a new ramp from I-270 South to I-44 West, addition of a pedestrian bridge over the Meramec River, and general traffic flow improvements for one of the busiest interchanges in the St. Louis area.

Poplar Street Bridge Widening

In order to alleviate congestion and improve the structure to lengthen it’s life, this unique project will accomplish both in roughly two years. The project includes complete replacement of the ramp from I-44 to the Poplar Street Bridge, removal of the asphalt surface on the PSB and replacing it with concrete paving, structurally tying the eastbound and westbound bridges together, widening the elevated sections of Eastbound I-64 and Route 3 South, and adding 9′-0″ to the PSB width. To complicate the project, this 9′-0″ is added between the EB and WB bridges, accomplished by sliding the entire 2,000 foot long…

Jefferson & I-64 Improvements

Downtown St. Louis development of a soccer stadium and NGA headquarters necessitated this project for the area, and KCI was tasked with building a new 22 nd Street interchange over I-64, replacement of Ewing Ave bridge, and new exit and entrance ramps for I-64. Work takes place next to and over active I-64 traffic, Metrolink and Amtrak tracks and the Union Station parking lot and includes 125,000 CY earthwork and 25,000 SY of concrete pavement.

Route 61 Troy Bridges

Existing bridges built in 1971 had been closed 5 times in the last 10 years due to flooding of the Cuivre River, and KCI began replacement of bridges and associated highway paving in Spring 2019. New bridges were built 5 feet higher than the existing, and bear on drilled shafts and steel pile. Bridges were constructed alongside the existing alignment to avoid traffic interruption, and then 150,000 CY of earth fill and 41,000 SY of concrete paving installed for the new alignment prior to removal of the original bridges.

Park Over the Highway

CityArchRiver 2015 had a goal of uniting our region and one of the world’s most recognizable icons with another of our greatest assets – the Mississippi River. KCI executed work for both MoDOT and the National Park Service to achieve this goal. We first completed the bridge that allowed visitors to walk from the Old Courthouse to the Arch grounds to the riverfront on one continuous greenway, without a curb or stair step in their way. The project scope included rerouting of traffic at the Eads Bridge and Washington Avenue and a new exit from I-55 North/I-70 West onto the…

I-64 Seismic Retrofit

In an effort to make an elevated section of I-64 in downtown St. Louis remain standing during an earthquake, MoDOT awarded the second to last phase of this project to KCI, which was the second for KCI. This package included seismic upgrades on the section of highway from 7th to 11th Streets, and painting of all structural steel from 7th to 14th Street. This congested area of downtown St. Louis required us to coordinate working in the parking lot of the General Services Administration, alongside and above Metrolink light rail tracks, above City streets, and next to Busch Stadium. Constant…

Loop Trolley Track

Description – In an effort to further revitalize an area of University City and the City of St. Louis, vintage trolley cars will soon be running on a new 2.2 mile long track system from the West end of the Delmar Loop to the Forest Park History Museum, by running East on Delmar and then South on DeBaliviere and back. Streetscape modifications will include boarding stations, landscaping, lighting and signals to further enhance this area. As part of the project, KCI will also replace a 4-span bridge over the live MetroLink tracks near DeBaliviere and Forest Park Avenue.

BJC Forest Park Parkway Improvements

With the new campus expansion of BJC Hospital in St. Louis will come additional traffic, and previously Forest Park Parkway (FPP) running under Kingshighway created traffic jams at FPP and Euclid. This project aimed to alleviate those jams and improve traffic flow, by raising FPP to become an at-grade intersection with Kingshighway. FPP was completely closed to traffic for the 9 month project duration, but Kingshighway was required to remain open for the duration. Project scope included a new pedestrian tunnel to access Forest Park, raising grade for the new FPP pavement, and filling under the existing Kingshighway bridge with…

Metro Downtown Transit Center

This project expands the Civic Center Transit Station in downtown St. Louis, where about 8,000 people board Metro buses and the MetroLink every day. The scope of the project included demolition of the existing station that could only accommodate 6 buses, allowing now for 14 buses at a time, while also improving ADA access to the MetroLink station, and adding a building that will house public restrooms, a waiting area, concessions area and a security substation.

Metrolink Facilities 5 Extension

Metrolink is the St. Louis metropolitan region’s light rail system comprised of 37 stations and 46 miles of track which serve the St. Louis area and St. Claire and Monroe counties in Illinois. In 2003, the rail system was expanded to the southwest side of St. Louis, and KCI was awarded a 1.3 mile section of this expansion. Along with site clearing and demolition of existing structures, KCI constructed five new bridges from 120 feet to 2,400 feet in length, setting 83 concrete and 88 steel bridge girders in the process. These bridges spanned Interstate 44, two railroads, Big Bend…

I-44 Bridges over BNSF

After the start of the project was delayed over a year due to bridge re-deign initiated by the Value Engineering process with MoDOT, the project started in Spring of 2017. The three-span bridges were designed to be simpler single spans, thus saving money, time, and coordination with the railroad that runs beneath the bridges. In 2017, all traffic on I-44 is shifted onto the eastbound bridge, and the westbound bridge replaced with a new steel girder structure. Upon completeion of that bridge in Fall 2017, traffic is restored to both bridges through the winter months. Then in Spring 2018 both…
