Zayo Group Holdings, Inc. announced plans to extend its long haul dark fiber network between Salt Lake City and Sacramento. The network expansion will add more than 800 route miles to Zayo's owned long haul network which spans more than 16,000 route miles across the United States and Europe. The project is currently under construction and is expected to be completed in the fourth quarter of 2015.

The network expansion will complement Zayo's existing long haul network and will enable connectivity between major West Coast data center markets such as Los Angeles, Seattle and the Bay Area and major data center markets across the rest of the United States. Zayo will offer its full range of Dark Fiber, Wavelengths, Ethernet and IP services across this route.
