Finley Receives Two ACEC Awards
The first award was for the US 281 Bridge over the Colorado River in Marble Falls, Texas, a 958-foot Cast-In-Place Segmental Bridge.
The Archer Western (WALSH) - FINLEY team proposed design modifications and means and methods changes that exceeded all the expectations of the Texas Department of Transportation (TxDOT) and the public, provided a stunning signature bridge that was more efficient to build and saved $2 million dollars. The New US 281 Bridges over the Colorado River are the second longest segmental bridges in Texas.
"In any new project, including this signature bridge for Marble Falls, TxDOT looks to balance design, function, operations, maintenance and most importantly, safety while still providing the same product or better. The public was very sensitive to the aesthetics of this bridge, since the lake is also used for recreation. The Contractor put together a great team and the alternative concepts developed by the Contractor and Construction Engineer helped to meet the expectations of TxDOT and the public." Howard Lyons, P.E., TxDOT Area Bridge Engineer
The second award was for the I-35 Brazos River Bridges in Waco, Texas.
The TxDOT selected an extradosed bridge which is a hybrid structure that combines elements of a steel box girder, reinforced concrete deck and cable-supported superstructure. Although fairly common in other countries, extradosed bridges are rare in the United States. The new bridges used an innovative design which is highly aesthetic, durable and cost-effective. This project was completed on budget and four and a half months ahead of schedule prior to Baylor University's football season and the opening of the new stadium. The new bridges now provide increased mobility and safety and are a regional landmark for the local community and traveling public.
FINLEY provided construction engineering analysis to The Lane Construction Corporation. Services included: steel girder erection design; temporary support works design, three dimensional time dependent analysis (used for cable analysis), construction manual, sequence and stay cable stressing.
"These frontage road bridges are a specialized type called "extradosed", a combination of girder and cable construction. It is the first extradosed bridge in the nation using a steel superstructure, which adds an extra complexity in maintaining the stay forces during construction," said Kirk Krause, P.E., TxDOT Area Engineer.
