The Merritt Parkway construction began in 1934 and by June 1938 the first 17.5 miles of the parkway were opened to the public. This highway was designed to make the roadway blend in with the topographic scenery of the surrounding area.
Work on the bridges include the restoration of the historic metal railings. All bridge repairs and safety improvements are designed to maintain the unique appearance of each structure.
The maintenance of the existing plantings and additional plantings will be in accordance with the Merritt Parkway Landscape Master Plan.
