Other forms of transportation while you await the L train’s reopening include:
Taking the NYC ferry
Taking the G line into Queens, and then transferring to take the 7 into midtown (the G line is said to be doubling from four cars to eight.)
Alternatively, some companies have thought up other solutions for commuters, such as the aptly named The New L, a carpool subscription that will get you to work in a Mercedes-Benz Sprinter van. There have even been talks of perhaps creating an air gondola, or a temporary pontoon bridge.
