While outlining her agenda for a “revitalized” Boston to hundreds of business leaders Thursday morning, Boston Mayor Michelle Wu said “enough is enough” on Boston’s failing transportation infrastructure and crowded roads.

“As a mom, I tell my kids, whether it’s to get them to clean their rooms or finish their dinners properly, ‘What you don’t do now, you’re going to have to do later,’ ” Wu said in her first speech to the Greater Boston Chamber of Commerce as mayor. “I think with our transportation system, what we are experiencing now is what we didn’t do before. Those investments that were deferred, the maintenance that was delayed, that piles up and ends up costing a lot more for all of us.”

Following a month of major MBTA closures, and the threat of future shutdowns that transit officials say are inconvenient but necessary, Wu said she plans to have the City of Boston get more involved in obtaining funding for the state-run transit authority.

“It’s a little bit unusual that cities get involved, but this will be transformational. These infrastructure changes are needed immediately,” she said.

The city threw its weight behind a proposed Allston megaproject alongside the state, jointly applying for nearly $1.2 billion in federal grants under a new federal infrastructure law that would go toward a massive roadway, rail and pedestrian overhaul of a narrow stretch near Boston University. Wu added that public transit improvement and better walkability will help take cars off the road to decrease the traffic congestion that chokes Boston roads.
