Grove Road Underpass at KCS Railway -Richardson, Texas
1998 American Public Works Association Project of the Year, for structures less than $2 million. Owner - City of Richardson, Texas.
Architectural treatments included a Reynobond aluminum composite
superstructure cladding, Cultured Stone fascia, exposed aggregate
concrete and extensive landscaping. Inspection access is provided
via hinged doors in the superstructure and bent column cladding.
With an active, in-use railroad track running through the middle of the
construction project, careful timing and sequencing of events were
essential to complete this award-winning project.
The height of the existing embankment combined with insufficient room
adjacent to the site prevented the economical construction of a shoo-fly
to detour train traffic and allow conventional bridge erection techniques.
Extensive negotiations with the KCS Railway resulted in only two 24-
hour periods allowed for rail traffic interruption. Precast concrete abutment
and bent caps were joined via steel weldments to concrete drilled shafts
placed during openings in rail traffic. The two steel superstructure spans
were built on-site and lifted into place during the second service interruption.
