BCEO ROUNDABOUT PROJECT WINS AWARD
Hamilton Mason - Liberty Fairfield Road

The Butler County Engineer's Office has received an award for its Hamilton Mason Road roundabout project at Liberty Fairfield and Vinnedge Roads. Presented by the American Society of Highway Engineers' (ASHE) Triko Valley chapter, the Donald C. Schramm Transportation Improvement Award recognizes this innovative BCEO project in the category of construction projects costing under $2 million.

Completed last year, the project consisted of building a modern single lane roundabout on Hamilton Mason Road at Vinnedge Road and realigning Liberty Fairfield Road to intersect with Hamilton Mason at the new roundabout. It was one of two major roundabouts constructed by the BCEO in 2008.

"What made this project unique was the way it came about and the significant cost savings to our taxpayers," said Butler County Engineer Greg Wilkens. The pre-existing conditions consisted of Liberty Fairfield and Vinnedge Roads being offset at Hamilton Mason with limited sight distance and vehicles backing up during rush hours. The original plan was to relocate Liberty Fairfield Road to align with Vinnedge at Hamilton Mason, creating a traditional 4-way intersection with signals. Due to the sloping, uneven terrain in the area however, vertical alignment issues would be a problem. To correctly engineer a conventional intersection would have meant extending the project limits farther west. That would have required replacing a bridge, purchasing additional right-of-way from private property owners, and increasing the amount of materials and asphalt used. Additionally, it would have increased the amount of time and labor hours paid to complete the project.

BCEO design engineers began to study the modern roundabout option and concluded that it would not only be a safer alternative but that it would reduce the overall scope of the project, thereby cutting the total project cost nearly in half. The final price tag for the project was $958,351.

The roundabout allows traffic to move more efficiently and with greater safety through all four legs of the intersection, acting as a traffic calming device. Of particular note, motorists now tend to enter residential areas along Vinnedge and Liberty Fairfield at slower speeds.

"Roundabouts are still a relatively new concept in this region and we here in Butler County are among the first to implement them," Wilkens noted. "Traffic studies have proven their benefits and they are rapidly gaining popularity throughout the country for their ability to move traffic safely and efficiently when utilized in the right locations. We're pleased that our local ASHE chapter has recognized this important project."

Roadway and bridge projects are submitted for the Schramm Transportation Award based upon unique characteristics and difficult challenges such as special construction techniques, maintenance of traffic, and funding and right-of-way issues.
