Plans are underway to widen Lake Cook Road between Hastings Lane and Raupp Boulevard to six lanes to improve traffic flow and safety in Buffalo Grove.
"Lake Cook Road carries approximately 53,000 vehicles per day," said Darren Monico, Buffalo Grove village engineer. "The segment of Lake Cook Road between Raupp Boulevard and Hastings Lane is not only a serious traffic bottleneck but it is also a high-crash area. More than 750 crashes have occurred in this segment between 2006 and 2010."
As a result, the village has been working with the Cook County Department of Transportation and Highways on a study of the county road that provides a major east-west thoroughfare through the village.
"The project will expand the existing roadway to include an additional travel lane as well as required left- and right-turn lanes to accommodate the high traffic volumes and provide congestion relief," said John Yonan, county superintendent of transportation and highways.
Phase I of the study evaluated the proposed increase to three lanes in each direction just east of Raupp Boulevard and the addition of dual left-turn lanes and some right-turn lanes at major intersections. The improvement will also include realignment and extension of Weiland Road south to Buffalo Grove Road.
Results of the study, which began in 2008, will be discussed at a public hearing in Buffalo Grove in late summer or early fall, Monico said. Final approval of the Phase I study, which includes an environmental-impact assessment that must be approved by the Federal Highway Administration and project designs that must be approved by the Illinois Department of Transportation, is expected by late 2013 or early 2014.
The Buffalo Grove Village Board also approved an intergovernmental agreement with Cook County this month to begin Phase II, which will create the designs for the project. The cost is estimated at $53.5 million for construction, right-of-way and engineering, Monico said. The village will be responsible for utility relocation, and that cost has not been determined, he said. Construction could begin in 2016 and last through 2018.
The village was not obligated to contribute any money to Phase I of the study, Monico said. However, the Village Board approved $112,556 toward Phase II of the engineering study, which will cost Cook County $3.3 million. The Cook County Board is expected to review this project at its July meeting.
Monico said the Lake Cook Road improvement plans do not affect any residential housing or businesses along the road.
"The project scope was defined based on locations with the greatest need," Yonan said. "We also took into consideration the financial constraints with a large capital improvement project. The county secured federal surface transportation program funding for a total of $8 million and an additional $12 million through federal Congestion Mitigation and Air Quality Funds. The county is seeking additional funding from Lake County and the Illinois Department of Transportation."
According to the intergovernmental agreement between Buffalo Grove and Cook County, Phase II design engineering will include data collection and coordination with various agencies, municipalities and utility companies; preliminary engineering preparation of right-of-way documents and coordination meetings; preparation of construction plans, specifications, estimates and contract documents; project administration coordination with regulatory agencies; and permit acquisition, construction assistance, shop drawing review and meetings.
Civiltech Engineering Inc., which coordinated Phase I, is expected to manage Phase II as well, according to the agreement.
