Yellow Line Extension

About the Project: Alternatives

Several alternatives, which included alternative routes and alternatives to rail transit, were considered during the Alternatives Analysis process. The alternatives were then narrowed through public and agency feedback to the three alternatives described below. The Locally Preferred Alternative (LPA) includes 1.6 new route miles of rapid transit from the existing Yellow Line, reconfiguration of the existing Dempster Station and one additional station at Old Orchard Road with new bus access and parking facilities.

 

Locally Preferred Alternative (LPA)

The proposed LPA would extend the heavy rail transit line from Dempster Station north along the Union Pacific Railroad (UPRR) right-of-way from Dempster Street to the vicinity of Old Orchard Road.

Summary:

The Locally Preferred Alternative would proceed northbound on a single track alignment within the UPRR right-of-way from Dempster Street to the area north of Golf Road. Beginning north of Golf Road, the alignment curves east, paralleling the east side of the Edens Expressway on an elevated profile to the proposed terminal location on the south side of Old Orchard Road. The elevated profile avoids grade crossings between Dempster Street and Old Orchard Road.

The Locally Preferred Alternative would include the following features:

No Build Alternative

The No Build Alternative is defined as the existing transportation system, plus any committed transportation improvements that are already in the Chicago Metropolitan Agency for Planning Fiscal Year 2007-2012 Transportation Improvement Program (TIP). Intersection improvements at Dempster Street, Golf Road and Old Orchard Road along Skokie Boulevard are included in the TIP, as well as road widening improvements of Old Orchard Road from Harms Road to Skokie Boulevard and the expansion of the northbound Edens off-ramp lanes. In addition to a variety of resurfacing projects, Dempster Street is scheduled to be reconstructed and widened to Central Road. All elements of the No Build Alternative are included in each of the other alternatives.

Transportation System Management (TSM) Alternative

The proposed TSM Alternative is a Bus Rapid Transit (BRT) alternative that operates between the Yellow Line Dempster Station and Westfield Shoppingtown Old Orchard Mall via Dempster Street, Niles Center Road, Skokie Boulevard, Golf Road and Lavergne Avenue.

Summary:

The Transportation System Management Alternative would operate in mixed traffic with traffic signal priority on the Dempster Street, Niles Center Road, Skokie Boulevard and Golf Road portion of the route.

The Transportation System Management Alternative would include the following features:
