Thanks to reader Liz Patek for these shots of DOT crews getting to work this morning at Broadway and Amsterdam at W. 71st Street. Dubbed the “bowtie of death” by Manhattan Borough President Scott Stringer and Assembly Member Linda Rosenthal, the foreboding expanse of asphalt has seen dozens of crashes over the last two years, and has been named by Transportation Alternatives as the most dangerous intersection on the Upper West Side.

The city promised a number of safety improvements just under a year ago, and in July Rosenthal and Stringer again called for their implementation. We’ll keep you posted now that construction has begun.

Update Sep. 2: NYC DOT sent along a more recent project rendering than the one we originally posted. See it after the jump.
