Here’s a photo I took at about 8:20 this morning from the southern edge of the Brooklyn Heights Promenade, showing traffic as it merges into two lanes from three where the lane restriction begins. The flow continued normally – I looked over the side of the Promenade at the traffic heading north, and it continued to flow.
Here’s another photo, from about 7:20 this evening. Traffic is heavier, but it continues to flow smoothly.
I didn’t do an exhaustive survey, but didn’t notice any abnormal traffic increase on any of the streets in the Heights. Please let us know if you had, or are having, any such experience.
