When MnDOT originally looked at the costs to widen this bridge, MnDOT broke the cost down into three different groups, excluding any costs off the bridge. 1- Median replacement and deck repair work 2 -Widening costs (abutments, pier, beams) 3 -Approach panels and staging Work Type East Side Cost West Side Cost Median/Deck $180,000 $180,000 Widening $280,000 $625,000 Approach/Staging $150,000 $200,000 $610,000 $1,005,000 So, as you can see,the additional costs for widening to the west were almost$400,000. This increase in cost was based on the need for additional beams, deck widening, abutments and piers.And,the beams would need to be of a different size to account for meeting clearance under the bridge. Also,this increase in cost does not account for any costs to modify any signals or construction of trails that lead up to the bridge. Because of the large cost difference, MnDOT preferred the trail remain on the east side of the bridge. Please let me know if you have any questions. Thanks mark 1
