In December, the CTA announced its selection of Fluor Corp. and Walsh Construction Co. to engineer, design and build the first phase of the RPM project. The two will work together as a joint venture under a $1.2 billion contract, which includes reconstruction of four stations and six miles of old track; construction of a $570 million rail bypass, also known as the Belmont Flyover; and installation of a new signal system. Construction on the Belmont Flyover is not expected to start until next year.
