The new Mohegan Avenue retaining wall is now complete in Yorktown.
Crews replaced 600 feet of retaining wall along Mohegan Lake with erosion and sediment-control devices to protect the water quality.
Yorktown officials say the improvement is another example of how the town continues to push toward eco-friendliness.
They say the work was completed by an Ossining contractor under the proposed budget, and about three weeks ahead of schedule.
