@metrolinktrains: 18 million pounds. One weekend. And even a little rain couldn’t stop the work. 👏 During the Oct. 10–11 OC and IEOC Line closure, crews rolled the massive concrete box for the future Marine Way Undercrossing into place beneath the OC Line tracks, using an innovative construction approach that is still uncommon for rail projects on the West Coast. The new undercrossing will ultimately create a connection for drivers, pedestrians and bicyclists, improving access to the Great Park and surrounding Irvine communities. A big thank-you to the crews and project partners who worked through the rain to get it done on schedule. 🚧👏
