Which Midtown Tower Was Evacuated? The Buckling NYC High-Rise, Explained — Address, Cause and Is It Safe Now

UPDATE (July 9): Developer MetroLoft says it has “identified the issue” with the former Pfizer building at 235 East 42nd Street, per PIX11, as shoring work continues. The frozen zone around the tower is still being adjusted block-by-block — check DOB/NYPD notices before heading into the area.

The building evacuated in Midtown Manhattan is 235 East 42nd Street — the 37-story former Pfizer world headquarters between Second and Third Avenues, one block from Grand Central Terminal and the Chrysler Building. On Tuesday morning, July 7, construction workers converting the vacant office tower into apartments spotted two steel support columns buckling near the 21st floor, with beams bending and upper floors visibly sagging. Fearing a partial collapse, the city evacuated the tower and surrounding buildings and froze off several blocks of Midtown East. By late Tuesday night, officials said the building is “stable” for now, though a restricted zone remains and crews are still reinforcing the structure. No injuries have been reported.

What Happened at the Midtown Tower? A Timeline

Per NBC News, The New York Times, CNN, ABC7 and amNewYork reporting:

• Just before 8 a.m. Tuesday: 911 calls came in from the construction site at 235 E. 42nd St. after workers observed structural support beams beginning to buckle; falling debris was reported inside the building.
• The damage: The New York Times reported workers rushed to evacuate as “beams started bending” and floors sagged. Officials said two columns buckled between the 21st and 22nd floors, with damage and sagging spanning roughly floors 21 through 26.
• Tuesday afternoon: City officials warned the tower had “continued to move” since crews arrived and was “not yet stable.” Mayor Zohran Mamdani announced a “frozen zone” around the site and urged New Yorkers to stay away.
• Tuesday night: After emergency jacks and new steel went in, Buildings Commissioner Ahmed Tigani told reporters, “I can say right now the building is stable,” noting no movement for several hours.
• Wednesday, July 8: Officials said they are “confident” the temporary shoring is holding, per CNN, as work continues.

Which Building Was Evacuated in Midtown, Exactly?

235 East 42nd Street is a 1960s-era office tower designed by Emery Roth & Sons that served for decades as the global headquarters of pharmaceutical giant Pfizer. The building is now empty of tenants: developers Metro Loft and David Werner are converting it — together with the adjoining 219 East 42nd Street — into roughly 1,602 apartments, about 400 of them affordable, with completion expected in 2027. Trade outlets including Commercial Observer describe it as the largest office-to-residential conversion in U.S. history.

The tower sits in one of the busiest corridors in the country: a block east of the Chrysler Building, between Grand Central Terminal and the United Nations headquarters — which is why a structural emergency here shut down so much of Manhattan within minutes.

Why Was the Midtown Tower Evacuated? The Reported Cause

As part of the conversion, the upper 15 floors — beginning at the 22nd — are being expanded outward so they extend wider than the floors below. Nathan Berman, founder of Metro Loft, said that work is what overloaded the steel: “This additional load that we put on those floors caused those two particular columns to collapse.”

That is the developer's explanation — the city's Department of Buildings has not issued its own findings yet and is investigating the failure. Officials credited workers on site for catching the buckling before any collapse occurred.

What Streets Are Closed in Midtown?

Mayor Mamdani's initial “frozen zone” covered 40th to 45th Streets between First and Third Avenues, closed to both pedestrians and vehicles. As stabilization progressed, the closures narrowed. As of Wednesday, July 8:

• Vehicle traffic remains restricted on 42nd and 43rd Streets between Second and Third Avenues.
• Four nearby buildings remain fully evacuated, and a fifth is under partial evacuation affecting ground-floor businesses, per CNN.
• Tuesday's evacuations included several East 43rd Street addresses, 815 Second Avenue and a nearby Hampton Inn, per ABC News and amNewYork; about 400 children at a school on East 43rd Street were relocated safely.

Some evacuated office workers have been told it could be weeks before they regain access. Expect detours around Grand Central and check NYC DOT and MTA alerts before traveling.

Is the Midtown Building Going to Collapse? What Officials Say Now

The official language shifted from alarm to cautious relief within 24 hours. Early Tuesday, officials said the building was unstable and still moving. By nightfall, Commissioner Tigani said crews had safely reached the 21st floor, movement had stopped for several hours, and the building was stable — an assessment NBC News summarized as “stable” for now.

The qualifier matters. Emergency jacks and temporary steel shoring are carrying the load while permanent reinforcement is installed, and no further movement has been detected — but the restrictions stay until the Department of Buildings is satisfied the structure is fully secured.

What Happens Next?

Crews will keep adding shoring and new steel over the coming days, and the DOB and FDNY are going building by building to determine when evacuated neighbors can safely return. A full DOB investigation into why the columns buckled — and scrutiny of the conversion project's engineering — follows. This is a developing story, and this page will be updated as officials release new information.
