(Silver Award)   NY Gateway Connections Improvement Project – U.S. Peace Bridge Plaza, Buffalo, N.Y.

Contractor:  Surianello General Concrete Contractors, Inc.           

Owner: New York State Department of Transportation – Region 5             

Engineer:  Parsons Transportation Group of NY, Inc.                       


Surianello General Concrete Contractors, Inc.* was awarded the contract to improve access to and from the U.S. Border Port of Entry at the Peace Bridge Plaza, in Buffalo, N.Y.  

The project was awarded under the auspices of the Federal Highway Administration, in cooperation with the New York DOT, and in accordance with the National Environmental Policy Act.

The primary goal was to address the limited direct access between the Plaza and Interstate I-190.

Existing direct access is limited and requires regional and international traffic to use the local street system.

This limited access adds additional commercial traffic to the local streets, which were originally designed to only meet the needs of local traffic. The aim was to reduce the use of the local streets by interstate traffic and provide improved access to the existing plaza.  

The project was bid as a “design-bid-build best value,” as determined by an evaluation committee working under the direction of the New York DOT’s Contract Management Bureau. Submissions were scored according to best value scoring criteria. A combination of the technical submission (comprised of five technical sections) and price proposal was used to award the contract based on “Best Value.”

The $5.4 million project included placement of 19,200 SY of 10 in. concrete pavement for a total of 2.72 lane miles.  The existing pavement and foundation were removed and was found to consist of asphalt, concrete foundation pavement, cobblestones, and stone base material. The concrete foundation material was brought to a crushing operation and 12 inches of recycled base coarse material was installed and compacted.

The project proved to be more than the best value; it was incorporated innovation, creativity, and a commitment to sustainable construction practices.  Surianello used recycled concrete as an alternative for the base course. The contractor also used colored concrete for a concrete roundabout, which was originally designed in asphalt. 

Visitors and other motorists crossing the border at the U.S. Peace Bridge Plaza, as well as motorists and businesses in the surrounding area, now have greater access, thanks to high quality, durable concrete pavement.


(Gold Award)  State Highway 119 Reconstruction, Longmont, Colo.

Contractor:  Castle Rock Construction Company

Owner:  Colorado DOT – Region 4            

Engineer: Colorado DOT – Region 4, Boulder Residency   

State Highway 119 between I-25 and County Line Road is a growing corridor north of Denver that connects Longmont to Boulder and the surrounding cities. This 4-mile highway project included placement of 200,000 SY of 9 in. dowelled concrete pavement; 75,000 SY of full depth reclamation; and   placement of 18,000 CY of riprap. The project also included bridge resurfacing on two structures and the construction of new approach slabs; 75,000 CY of embankment material; and 135,000 SY of pavement removal.

The original completion deadline was the summer of 2017, but crews met high production goals and aggressive schedules, resulting in project completion in December 2016. This limited the adverse impact on the traveling public, and allowed the bride to be open to traffic early, alleviating the need for dangerous work zones through winter and spring.  

An innovative adaptive traffic signal system which reads traffic flows and changes the timing on signals also helped keep the traveling public moving during the project. 

One of the challenges on this project was the complexity of work in live waterways. The 2013 floods in Colorado caused scouring around bridge piers in the St. Vrain Creek and the Idaho Creek box culvert.

The Colorado DOT’s emphasis was not only on rebuilding the roadway, but also repairing flood damage, and preparing for future flooding. The design solution for the prevention of future damage was placement of riprap on the slopes for over a mile and around the structures in the waterways. 

CRCC used inflatable coffer dams to divert water and worked in phases in order to keep the water flowing as they completed the work.

In addition to completion well ahead of the schedule and on budget, the pavement is very smooth and along with the other work by CRCC, is very aesthetically pleasing.

Safeguards were built into the project to prevent damages from another flood event, and so, this concrete highway is expected to serve the people of northern Colorado and traveling public for decades to come.
