P P ti,�'�a�:�� . ,, 1500 West County Road B-2 � Roseville, MN 55113 Re: City of Orono—Ferndale Road Bridge � � Existing MnDOT Bridge No. L8854 Proposed MnDOT Bridge No. 27B12 S.A.P. No. 152-080-01 Our File No. 139-03-132 � Dear Dan: • I am writing regarding the variance that the City of Orono will be requesting for the bridge replacement. Once we have an opportunity to discuss the variance,the City Council will consider a resolution regarding the variance. � The project in question involves replacing an existing 22-foot wide bridge in Orono. The bridge serves primarily local residents that are traveling to or from CSAH 15 to the west of the bridge. East of the bridge, Ferndale Road continues to downtown Wayzata. Included with this letter are some photos of the project area and a map showing the project location. � . Variance Requested � � MnDOT design standards for rural bridges calls for a minimum of 12-foot lane widths and 4-foot shoulders. The curb to curb width of the bridge is the sum of the lanes width and shoulder widths plus four feet. This would require a minimum curb to curb width on the bridge of 36 feet. We are requesting a variance from Rule 8820.9920 to allow two 12-foot lane widths and 2-foot shoulders. The specific variances requested are: � 1. Two 11-foot wide traffic lanes and 2-foot wide shoulders on each side in lieu of the � minimum 12-foot wide traffic lanes and 4-foot wide shoulders required; and • 2. A 26-foot wide bridge roadway (curb to curb) in lieu of the minimum 36-foot wide � bridge roadway required. 2335 West Highway 3G . St. Paul, MN 55113 . G51-G3G-4G00 . Fax: G51-G3G-1311
