Morton Arboretum


David Woodhouse / Christopher E. Burke Engineering

Leveraging our proven expertise in demanding, limited-time-window commercial projects to complete a new entrance bridge for the Morton Arboretum with a minimum of disruption.

An increasing number of private and civil clients are turning to ICC for their infrastructure projects. Our position as an established provider for highly demanding commercial clients like Class 1 railroads makes us an ideal partner—we offer broad, technical expertise with the ability to deliver quality within narrow operational windows.

One example: construction of a new 240' long, 44.5' wide, four-span entrance bridge over the East Branch of the DuPage River for the Morton Arboretum in Lisle, Illinois. 

The bridge consisted of a cast-in-place deck over 30" web girders. The superstructure rests on H piles and cast-in-place piers surrounded in decorative masonry. The bridge includes architectural features to beautify the structure and blend it with the existing architecture. A pedestrian path on the north side connects the bridge with a path along Illinois Route 53 and pedestrian paths within the arboretum.
