Removal of Existing Bridges E-16-HF and E-16-HE over 32nd Avenue and Replacing Them With New Bridges E-16-HFA and E-16-HEA

The project is located on I-70 over 32nd Avenue in the City of Wheat Ridge. It begins at MP 264.15 and extends one half mile to MP 264.65. The work includes the removal of existing bridges E-16-HF and E-16-HE over 32nd Avenue and replacing them with new bridges E-16-HFA and E-16-HEA. Improvements include cross slope correction planning for ultimate superelevation correction of the curve to the south and median buildout to accommodated the detour and the ultimate I-70 configuration. This work will match the span configuration of the new clear creek crossing ramp bridge E-16-XX, which accommodates the ultimate widening of 32nd Avenue by the City of Wheat Ridge 201-00000 Clearing and Grubbing 1.000 L S 202-00026 Removal of Slope and Ditch Paving 583.000 Sy 202-00210 Removal of Concrete Pavement 1,600.000 Sy 202-00220 Removal of Asphalt Mat 2,622.000 Sy 202-00240 Removal of Asphalt Mat (Planing) 19,195.000 Sy 202-00246 Removal of Asphalt Mat (Planing) (Special) 2,308.000 Sy 202-00401 Removal of Bridge (Special) 2.000 Each 202-05008 Sawing Concrete (8 Inch) 1,256.000 Lf 203-00010 Unclassified Excavation (Complete in Place) 1,074.000 Cy 203-00060 Embankment Material (Complete in Place) 487.000 Cy 206-00000 Structure Excavation 2,208.000 Cy 206-00100 Structure Backfill (Class 1) 1,354.000 Cy 206-00360 Mechanical Reinforcement of Soil 1,354.000 Cy 207-00704 Subgrade Soil Preparation 4,082.000 Sy 208-00070 Vehicle Tracking Pad 8.000 Each 208-00207 Erosion Control Management 385.000 Day 214-00008 Extended Landscape Preservation 1.000 L S 304-06007 Aggregate Base Course (Class 6) 680.000 Cy 403-00720 Hot Mix Asphalt (Patching) (Asphalt) 63.000 Ton 403-09221 Stone Matrix Asphalt (Fibers)(Asphalt) 3,432.000 Ton 403-33841 Hot Mix Asphalt (Grading S) (100) (Pg 64-22) 2,606.000 Ton 408-01100 Joint Sealant 616.000 Lf 411-10255 Emulsified Asphalt (Slow-setting) 1,737.000 Gal 502-00100 Drilling Hole to Facilitate Pile Driving 90.000 Lf 502-11489 Steel Piling (Hp 14x89) 2,325.000 Lf 503-00036 Drilled Shaft (36 Inch) 949.000 Lf 506-00206 Riprap (6 Inch) 221.000 Cy 507-00100 Concrete Slope and Ditch Paving (Reinforced) 23.000 Cy 515-00120 Waterproofing (Membrane) 3,676.000 Sy 515-00400 Concrete Sealer 1,196.000 Sy 601-04550 Concrete Class G 1,659.000 Cy 601-40400 Structural Concrete Stain 1,510.000 Sy 602-00000 Reinforcing Steel 33,025.000 Lb 602-00020 Reinforcing Steel (Epoxy Coated) 359,841.000 Lb 603-01185 18 Inch Reinforced Concrete Pipe (Complete in Place) 168.000 Lf 606-00302 Guardrail Type 3 (31 Inch Midwest Guardrail System) 925.000 Lf 606-00930 Guardrail Type 9 (Style Cd) 391.000 Lf 606-00940 Guardrail Type 9 (Style Ce) 350.000 Lf 606-00941 Guardrail Type 9 (Style Ce) (Special) 158.000 Lf 606-01403 Transition Type Br9-gr9 4.000 Each 606-10900 Bridge Rail Type 9 860.000 Lf 606-20014 Tensioned Cable Barrier (Tl-4) 1,023.000 Lf 606-21010 End Anchorage (Tensioned Cable Barrier) 4.000 Each 607-53137 Fence Chain Link (Special) (36 Inch) 430.000 Lf 613-00200 2 Inch Electrical Conduit 3,690.000 Lf 613-04100 Electrical System Modifications 1.000 L S 613-10000 Wiring 1.000 L S 618-01992 Prestressed Concrete Box (Depth Less Than 32 Inches) 15,136.000 Sf 620-00005 Field Office (Special) 1.000 Each 620-00012 Field Laboratory (Class 2) 1.000 Each 621-00450 Detour Pavement 6,260.000 Sy 621-00500 Temporary Bridge 1.000 L S 625-00000 Construction Surveying 1.000 L S 626-00000 Mobilization 1.000 L S 626-01113 Public Information Management (Tier Iii) 477.000 Day 627-00013 Pavement Marking Paint (High Build) 520.000 Gal 627-01010 Preformed Plastic Pavement Marking (Type I)(Inlaid) 1,155.000 Sf 630-00000 Flagging 2,400.000 Hour 630-00006 Uniformed Traffic Control (Vehicle) 360.000 Hour 630-00007 Traffic Control Inspection 155.000 Day 630-00012 Traffic Control Management 385.000 Day 630-80355 Portable Message Sign Panel 6.000 Each 630-80370 Barrier (Temporary) 5,600.000 Lf 630-85010 Impact Attenuator (Temporary) 6.000 Each 630-85040 Impact Attenuator (Truck Mounted Attenuator)(Temporary)2.000 Each
