There are a number of missing brick pavers forming a very large and potentislly dangerous pothole in the pedestrian plaza at Haymarket. The location of the hole is between the entrance/exit for the Green and Orange T lines and the crosswalk at Surface Rd. on the way to the North End. The hole formed by the missing bricks is both large and deep enough to cause a severe injury should someone step into it. Please replace the brick pavers.
