OUTSTANDING  CONCRETE ACHIEVEMENT AWARD
Presented  to
The Keystone Avenue Roundabout Interchanges at 106th St. and 126th St.
Carmel, Indiana

The  Indiana Ready Mixed Concrete Association (IRMCA) presented the 2009 Outstanding  Concrete Achievement Awards for projects in the State of Indiana on January 19,  2010 at the Indianapolis Marriott North at Keystone at the Crossing in  Indianapolis, Indiana.

In  the category of Concrete Infrastructure Projects - Bridges, the winner is the Keystone  Avenue Roundabout Interchanges at 106th St. and 126th St.  located in Carmel, Indiana.

The  project team is the City of Carmel, American Structurepoint, Milestone  Contractors, LP, Smock Fansler Construction, Jobsite Supply and ready mix  producer, Shelby Materials.

This  was the first of a multi-phase alteration of major intersections along Keystone  Avenue in Carmel. It included converting to roundabout style intersections at  each end of a new bridge that included decorative truck aprons, walks, bridge  plazas and medians.  The decorative  elements were comprised of three individuals colors and patterns separated by  sinuous bands of gray concrete, most of which also serves as a structural,  reinforced topping slab for the pedestrian areas of the bridge decks. Nearly  all 28,100 square feet of this project was placed under live traffic conditions,  within a tight schedule. The road closure window was only long enough to erect  bridges, lower Keystone Avenue, and build up the approach ramps. The decorative  work on both bridges was done simultaneously with two full crews in order to  meet the final deadline.

IRMCA  presents these awards to recognize extensive application or imaginative use of  concrete; and to honor the accomplishments of project owners, architects,  engineers, contractors, owners and ready mixed concrete producers.
