I-64 over Wabash River
Knight is
providing Phase I and Phase II engineering services for the major
rehabilitation and/or reconstruction of the dual bridge structures over
Wabash River for the Illinois Department of Transportation. Phase I work
will include data collection, pre-Phase I bridge studies, coordination
with all involved agencies and preparation of multiple environmental and
pre-design reports and assessments. Phase II work will include
preparation of Structure Geotechnical Report, Structure Reports, TS&Ls,
Plan Development Outlines, all necessary permits, coordination with all
involved agencies, prefinal and final construction plans, estimates and
special provisions. is required to address critical scour
conditions caused by a river realignment upstream. The structure design
will accommodate seismic conditions in a sensitive fault zone and may
also require raised profile to address increased freeboard
clearances for high crest storm events. |

Sheridan Road Bridge Reconstruction
When the historic
Sheridan Road Bridge became too weak and unsafe to support traffic
volumes, Knight designed a new bridge that combined modern structural
expertise with traditional design elements found in the existing
structure. Knight worked in close cooperation with the City of Lake
Forest and the Illinois Historic Preservation Society to remove and
replace the existing bridge with a new bridge featuring similar
architectural elements while meeting current safety standards. The
combination of old and new resulted in a bridge that complements the
historical significance of the surrounding area while meeting modern
safety needs. |

18th Street Pedestrian Bridge
In 2003, Knight was selected to design a
new pedestrian
bridge at 18th Street over the Metra tracks and under a busway on
Chicago’s lakefront, near Solider Field. The project was the
first design/build project undertaken by the Chicago Department of
Transportation and was built to coincide with the reopening of the
renovated Solider Field. Knight’s design consisted of a pedestrian walkway
connecting Calumet Avenue to the 17th Street underpass at Lake Shore
Drive, a new at-grade busway crossing of the Metra tracks, a new bus
turnaround and the removal of the existing timber pedestrian bridge.

U.S. Route 14
Knight provided
engineering services for the
reconstruction of U.S. Route 14 in Cary, Illinois. The project included
the construction of two new, permanent Union Pacific Railroad bridges
carrying Metra commuter tracks over U.S. Route 14 and Cary-Algonquin
Road. The existing grade separation carrying Cary-Algonquin Road over
Route 14 was removed and a complete channelized at-grade intersection
was constructed. This converted an existing Roadway-Railroad at-grade
into a full Roadway-Railroad grade separation. Two temporary structures
were constructed to maintain freight and hourly rail service throughout
the duration of the construction. Knight’s work included preparation of
construction documents for the realignment of Route 14, two fully
signalized intersections, five separate retaining walls, complex
maintenance of traffic, major storm sewer with in-line detention and
wetland of mitigation plans. |

College Avenue Bridge
Northern Illinois University selected Knight to provide engineering
services for the reconstruction of College Avenue. The reconstruction
project included repairs to the three-span continuous reinforced
concrete slab structure carrying College Avenue over the southern branch
of the Kishwaukee River. Knight's bridge work included deck repairs,
replacement of existing expansion joints, approach slabs and sidewalks,
utility coordination and landscape improvements. Because College
Avenue is located on the NIU campus, Knight worked closely with the
University to minimize impact to students, faculty and staff. |
