Metro will miss its Tuesday deadline to have all of its underground tunnels and stations wired for major cellphone carriers, but riders could end up waiting as long as three more years, the Washington Examiner reported.

Metro has remained publicly mum about whether it will meet the deadline.

“We are obligated to provide an update to the Hill by next Tuesday. We won’t be able to comment prior to the letter being transmitted,” spokeswoman Caroline Lukas said.
