Along Neptune Avenue, the city is installing watermains and sewer lines.

One goal is to prevent flooding that often happens during rainstorms; but fixing one problem is creating another. 

"The light turned green as I was crossing over here and I almost got hit by a car," said Kailey Clifford.

Residents said this stretch of Neptune has become a dangerous obstacle course for pedestrians, and it's especially troubling because many students at Mark Twain Intermediate School must walk through the construction zone to get to and from school. 

"It's really difficult. It'll usually take like five minutes just to cross one street. There are a lot of kids that need to walk to the train because there are a little amount of shuttles that our school has." 

Crosswalk markings are not clear, some curbs are missing.

One man had to act like a traffic agent just to coss the street.

But it's not just pedestrians who are aggravated, buses, trucks and cars all use this busy roadway.

"In the morning when we're trying to get this child to school by 8:11 okay, we cant' even get through," said Jacqueline Ahmed. "I detoured three blocks down, go down two blocks all the way to Mermaid and come all the way around just to get to Mark Twain. Every morning. This construction should be done at night. Not during school rush hour." 

The traffic jam is most severe where Neptune Avenue meets Cropsey Avenue, one of only two routes in and out of Coney Island. 

However hazardous it is for pedestrians, cyclists said they have it worse. 

"They force you to go into the street against traffic. The cars don't give you no courtesy. And you're forced to ride on the sidewalk like we're doing right now but the sidewalk is all broken."

Three city agencies, the Economic Development Corporation and the Departments of Tranportation and Design and Construction are overseeing the work, which began last august. 

Initially, when we called for comment, the agencies referred us to each other. 

At a minimum, residents said they want traffic agents posted here until the work is done, which is not expected until August 2019.
