• December 6, 2010—The City Council approved Resolution 82010-232 authorizing Supplement #1 to the Agreement with URS Corporation for the preliminary design of the South Shores Bridge over the Sand Creek Arm of Lake Decatur. The supplement was to complete the preliminary design to raise the bridge by approximately 3 feet. The expenditure for the services provided in Supplement #1 was not to exceed $57,200 which brought the total cost of the preliminary design agreement to $134,700. • July 5, 2011 —Council approved Resolution R2011-106 authorizing an agreement with URS Corporation to complete the final design for the replacement of the South Shores Bridge over the Sand Creek Arm of Lake Decatur and relocation of the Sanitary District of Decatur sewer interceptor at a cost of$219,200. Resolution R2011-107 was also approved authorizing $219,200 in Motor Fuel Tax funds to pay for the design services. BACKGROUND: South Shores Bridge Replacement The South Shores-Sand Creek Bridge was originally built in 1909. A new superstructure was placed on the old abutments in 1965. The foundation and abutments are 100 years old and the super-structure is 45 years old. Routine inspections carried out by City staff and various consulting engineers since 2004 have determined that the outside beams of this bridge are deteriorating and have moved with respect to the rest of the bridge. In August 2006,the Illinois Department of Transportation (IDOT) directed the City to place a weight restriction on the bridge and to perform follow-up inspections every 6 months to monitor the outside beams of the bridge. Since the damaged beams are not in the wheel path, the bridge is safe for normal traffic; however, the 6 month inspections show that the bridge's deterioration is increasing. The bridge needs to be replaced in the near term before stricter traffic restrictions are imposed. Public input gathered as part of the design process indicated a desire to raise clearance height of the replacement bridge. The City Council supported the proposal to raise the bridge by 3 feet. $1.04 million in Federal Surface Transportation Program—Urban(STU) funding is currently allocated to fund a portion of the bridge replacement cost. Current preliminary estimates show the bridge and roadway replacement cost approaching $2.4 million and the cost to raise the Sanitary District interceptor approaches $500,000. The Sanitary District has indicated a willingness to pay for the sewer costs. It is proposed that Motor Fuel Tax funds be used to fund the remainder of the work. Right of Way Acquisition Raising the new bridge by 3 feet requires a more extensive reconstruction of the roadway approaches. The roadway work requires five parcels of right of way and 3 temporary construction easements as described below and provided on the attached drawing: • Variable width of from five to fifteen feet of additional right of way on the south side of South Shores Drive, east of the bridge affecting 65 South Shores Drive. • Fifteen feet of additional right of way on the north side of South Shores Drive, east of the bridge affecting 54, 56, 60 and 62 South Shores Drive. • Three temporary construction easements. One west of the bridge and two east of the bridge affecting 50 and 62 South Shores Drive; and 1909 Shore Oak Drive. Page 12
