摘要：	A new bridge across River Kali was required as part of widening of NH 66 to four lane. A new 2 lane bridge was proposed on downstream side of existing bridge. The bridge length required was 665 same as that of old one. Old bridge had central 4 spans of 122 m. Two spans of 69.5 m and 19.5 m spans were on either ends. Foundations of old bridge are with single circular caisson foundations. Construction of old bridge was with in-situ cantilever construction method. Foundations penetrated through conglomerate stratum. The location had abounded twin circular caisson foundations for proposal with 48.78 m spans. Standing water depth was about 9 m. The new bridge had to comply with code specifications as that have changed over years and prevail now. Old bridge has pendulum hinge bearings for main spans and suspended spans for penultimate spans. These are no longer allowed. The paper describes how the final arrangement evolved after investigating probable fast construction.
