Title: Improvements to the I-90 and SR-252 Interchange
Sponsor: City of Westlake
Estimated Total Cost: $7,709,000
Proposed Source of Federal Funds: Ohio Statewide Urban Congestion Mitigation and Air Quality (CMAQ) Program
History/Background: In November 2012, the Director of the Ohio Department of Transportation (ODOT) announced the creation of an Ohio Statewide Urban Congestion Mitigation and Air Quality (CMAQ) Program. The intent of the program is to more quickly advance eligible projects that improve air quality, reduce congestion, and eliminate delay/improve safety, in addition to utilizing statewide CMAQ funding in the year funds are allocated. Selection of projects is in accordance with the policy established by the Ohio Statewide Urban Congestion Mitigation and Air Quality Committee.
The City of Westlake determined that several improvements are necessary within the Columbia Road (SR-252) and I-90 Interchange/Sperry Drive area (location map) due to the congestion and crash history at this location. The City had a Corridor Study prepared to analyze the conditions at the study area and to recommend potential improvements. The corridor study and public meetings were used to determine a preferred alternative to alleviate the congestion and safety problems in the study area. The preferred alternative included short, medium and long term solutions for the corridor.
The recommended short term improvements include revised lane use configuration of the eastbound movements at the Columbia/Detroit intersection. This alternative involves re-striping the eastbound direction to a standard configuration of 1 left, 1 thru, 1 thru-right turn lane. Signal timing will be optimized and traffic signs for the new lane configuration would be needed. The City of Westlake has completed these improvements.
Proposed Project: The proposed project involves medium and long term solutions for the corridor. The proposed medium term improvements identified for the study area include improvements to the I-90 westbound ramps and Sperry Drive. This recommendation eliminates the I-90 westbound to Columbia Road northbound exit ramp and combines this movement with the I-90 westbound to southbound movement utilizing the existing loop ramp. The I-90 westbound to Columbia Road southbound free flow exit ramp will continue to be used for southbound Columbia Road traffic.
In addition, the loop style exit ramp will be widened at the intersection to accommodate the additional northbound exit traffic to include one left turn lane and one through lane. The pavement markings on Columbia Road will be revised to eliminate the offset left turn lanes at the Sperry Road intersection. At this intersection, Columbia Road will be a four-lane section with one left turn lane and one thru-right lane northbound and one left turn lane, one thru lane and one thru-right lane southbound.
The long-term improvements recommended for the study area include improvements to the I-90
eastbound ramps. This recommendation reconfigures the existing I-90 eastbound entrance and
exit ramps to tight diamond style ramps. The spacing between the interchange ramps and Detroit Road increases from 200 feet to 600 feet. In addition, the I-90 eastbound entrance ramp geometric deficiencies are corrected as part of this alternative.
The project’s estimated total cost is $7,709,000. The estimated cost of right-of-way (RW) is $9,000. The RW will be funded locally. The estimated cost of construction (C) is $7,700,000. The sponsor is requesting eighty percent ($6,160,000) of the construction (C) cost to be funded with CMAQ funds. The sponsor will provide the twenty percent ($1,540,000) matching funds.
