Abstract:
During construction of the Ayalon Freeway in Israel, the new northbound lanes had to cross under the existing Haifa-Jerusalem railway track at about a 20 deg skew angle. The road and the railway both are curved. A single track, three span railway bridge was designed to match the alignment and levels of the existing rails. The 104 m long bridge is a curved, continuous-box-girder bridge that was cast in place and post-tensioned.
