The Battery Park underpass is completely flooded after Sandy slammed the city yesterday.
Getting to and from work during the next several days will be so harrowing that commuters will wish they had their crowded subway trains and traffic-choked tunnels.
Officials began the slow restoration of transit systems yesterday, but there are still weeks of work left before everything is back to normal.
For the next several days, drivers will have an easier time than those who take subways, buses, and commuter rails.
"I can say unequivocally the MTA [Monday] night faced a disaster as devastating as it has ever faced in its history," said agency Chairman Joseph Lhota.
LAKE LA GUARDIA: A passenger ramp at a La Guardia Airport terminal leads to nothing but water yesterday after Hurricane Sandy left the tarmac swamped. La Guardia and Newark will remain closed today, while Kennedy Airport will reopen for only a few flights.
"Sandy wreaked havoc . . . in every single borough of the city and every single county."
The storm was so powerful a 40-foot boat ended up deposited across the Metro-North tracks in Ossining.
The feds have stepped in to help — the Army Corps of Engineers will be in New York to clear flooding in the PATH train tunnels and the Brooklyn-Battery Tunnel.

The subway system could be shuttered for up to five days — and when it does return, it will be on a line-by-line basis.
"Rather than talk about restoration of the system, it's going to be more a conversation of restoration of parts of the system first," Gov. Cuomo explained yesterday.
The MTA said it will hold a midday briefing today to discuss a timetable for restoring service.
When asked how long the subways would be off limits, Mayor Bloomberg said a "good four or five days, I think. At this point, we don't know."
Downtown stations will likely be the last to open, because they suffered the worst damage.
The No. 1 line's new $500 million South Ferry station, for example, filled with water up to its ceiling.
Officials said every subway tube under the East River was flooded. The Joralemon Street tunnel, which handles 4 and 5 trains, was being pumped yesterday and should be cleared soon.
As for the commuter railroads, the MTA says it will restore partial LIRR service today.
The current plan is to bring westbound trains to Jamaica, where buses would take riders into Manhattan.
Officials are also trying to bring limited service back to the Metro-North today but are unsure whether it's possible because of serious damage.
The storm tossed a 40-foot power boat across four of the railroad's tracks.
NJ Transit will remain offline with no date set for service.
Amtrak said last night that it would run modified service between Newark and points south.
