~ Concrete overlay looked very good with no observable cracking.
~ At the time of the visit the contractor was removing the on-site detour fill material.
~ The bridge appeared to experience a significant amount of impact loading from truck traffic.
~ There were questions on the benefits of requiring a smoother transition from the roadway on to the bridge during construction, i.e. before the final lift of asphalt is applied.
~ Jacking the transverse post-tensioning strand from each end was suggested to improve the transverse force applied to the bridge.
A/I ~ The Structure Design Unit will plan a follow-up site visit to observe the condition of the overlay.
A/I ~ The Construction Unit will find other projects to try jacking the transverse post-tensioning strands from both ends and will provide feedback.
