The 10th & Salt Creek Bridge project included removal of the existing 364' x 36' bridge deck with steel super structure, replacing it with a 363' x 40'8" bridge deck with NU1600 super structure. Implementation of a temporary bridge spanning Salt Creek during demolition and new bridge construction was required. Project quantities included 2,240 SY of 9" doweled paving, 754 SY of which was hand placed with the remaining 1,486 SY machine placed. The project also incorporated 11,377 SF of sidewalk and bike trail. 15", 18" and 24" RCP pipe was removed and replaced with 6ea new inlets.
Construction of the south abutment and ballpark trail connector included excavation into a Levee Critical Area, which required monitoring of river levels electronically via a USGS collection device. Abutment 2 had a Level 3 fiber main somewhat close to the work zone, so temporary measures such as crane mats and battered pile surveys were done to successfully avoid a large utility hit.
A 56-day closure of the 10th & Miliary intersection was implemented during the reconstruction. To ease impact to the local community during construction and closure of the intersection, a considerable amount of temporary sidewalk and 24" CMP was utilized to allow pedestrians to access a bus stop and provide a path through the intersection throughout the project.
