A water main break caused widespread flooding and heavy infrastructure damage in Times Square on Tuesday.

The pipe was more than 127 years old, sending more than 1.8 million gallons of water pouring into the subways.

Its break is putting a renewed focus on the city’s aging infrastructure.

Last year, a team of engineers found that nearly 40% of the city’s pipes were placed prior to 1941.

To put that into context, there are more than 7,000 miles of water main lines under the city’s surface.

Vincent Lee, leader of the Americas East Civil and Water Team for Arup, which is an engineering firm dedicated to sustainable development, joined NY1 political anchor Errol Louis on “Inside City Hall” Thursday to talk more the city’s aging infrastructure.

“The infrastructure that we have right now is under a tremendous amount of pressure. We have aging infrastructure, we have high demands from a city that continues to grow,” Lee said. “The strides that we need to take around sustainability and reducing the efficiency and reducing the demands in a system that needs modernization, that needs futureproofing, is certainly one that we need to take on.”
