PITTSBURGH (KDKA) — Monday was the first day of delays and detours for “T” riders. The Port Authority is working on the tracks leading up to the Mount Washington Transit Tunnel from the South Hills Junction.

For a few riders, it was a case of the Mondays as they got to the South Hills Junction.

“I did hear about it, but I forgot until this morning,” Graham Pieniazek, from Mt. Washington, said.

“I was driving over and I was thinking, ‘Aww, jeez, the tunnel’s out,’” Tom Zytka, of Castle Shannon, said. “I remembered something about the 26th and I look and it’s the 29th.”

The Port Authority said the project should take about a month.

Their crews will work around the clock to replace about 500 feet of track between the South Hills Junction and Mount Washington Transit Tunnel.

“First, they have to dig up the concrete, replace the rail, and then re-pour the concrete,” Port Authority spokesperson Adam Brandolph said.

According to the Port Authority, inbound trains could be delayed by 20 minutes. They have to go up and over Mt. Washington through the Allentown neighborhood. Outbound trains could have longer delays.

About 10,000 “T” riders and 5,000 bus riders are impacted by the construction on weekdays.

“It’s a little bit of a bummer. It puts me behind, but my work is a little bit flexible, so it’s not the end of the world,” said Ryan, from Mt. Washington, as he waited for his “T.”

“It does impact it. I’ll probably end up driving downtown other than today because I forgot about it,” Pieniazek said.

Here are the detours:
