Abstract: When new pipeline construction requires the crossing of highways and railroads, a pipeline is generally installed in pipe or tunnel linear plate encasement which has been installed by bore-jack or tunnel methods under the highway or railroad right-of-way to avoid disruption of traffic and to avoid open-cut patches which often have settlement problems. Two projects are discussed which involved large diameter water transmission pipelines crossing highways and railroads: the installation of 121.9-centimeter (48 - inch) diameter tape-coated steel pipe in 167.6-centimeter (66-inch) diameter reinforced concrete pipe encasement in El Paso, Texas; and the installation of 152.4-centimeter (60-inch) diameter pretensioned concrete cylinder pipe in 243.8-centimeter (96-inch) diameter tunnel liner plate near San Angelo, Texas.
