EN HILLS MEMORANDUM DATE: January 17, 2012 TO: Honorable Mayor and City Councilmembers Patrick Klaers, City Administrator FROM: Terry Maurer, Public Works Director SUBJECT: Lexington Avenue Bridge Widening Background As part of the negotiated settlement with Mn/DOT for Municipal Consent on the I-694 project, Mn/DOT agreed to widen the Lexington Avenue Bridge to provide an ADA compliant pedestrian crossing. The agreement stated that Mn/DOT, Arden Hills and Shoreview would meet to discuss and decide the appropriate side (east or west) for the widening and pedestrian crossing. The first meeting was held at Shoreview City Hall on May 23, 2011, and was attended by Mark.Lindeberg from Mn/DOT, Mark Maloney from Shoreview and myself. There was general discussion at this meeting relating to a number of issues such as: • Widening to the east is more economical than the west due to the fact that it can be accomplished with one additional standard bridge beam. Widening to the west would require two special beams (widening to the west would require greater width because the east already has a narrow space available for pedestrians) to maintain proper clearance from the beam bottom to the interstate road surface below due to the grade of the interstate. • The Shoreview side has pedestrian facilities currently in place from County Road D to County Road J. • The Arden Hills side does not have pedestrian facilities in place from County Road F to Grey Fox Road. (It was indicated that the Arden Hills City Council would be willing to discuss construction of this infrastructure if the bridge was widened to the west) • Shoreview agreed to fund the realignment of the existing trails from the north and south ramps to the widened bridge if the widening was on the east side. i City Council Meeting C:\Users\sonj a.klingberg\Desktop\1-17-12LexingtonBridge Widening.doc Page 1 of 2
