The Neponset River Greenway trail will see its second bridge crossing installed this week, Department of Conservation and Recreation (DCR) officials said. A dramatic arched walkway over the Neponset River will complete the planned bridge installations for this stretch of the 1.3-mile extension.

Similar in style to the Blue Heron Bridge in Newton, the new Harvest River Bridge will function as a crossing connecting the Mattapan path to a trail on the Milton side of the river. The entire $14 million Neponset River Greenway extension is expected to be completed in October, said project manager Stella Lensing.

Officials said in April that the mechanics of installing the wooden Harvest Bridge would be less complicated than that of the canopy walk bridge portion already in place. Workers positioned the 60,000-pound walk 18 feet above the Mattapan trolley tracks on a chilly spring morning.

A sunny and warm morning looked to be in store for the installation of the Ipe timber-decked river bridge Thursday.

Members of the public are invited to watch the bridge installation from the adjacent Ryan Playground, DCR officials said. Construction is set to begin at 10 a.m., with a potential time frame of 2-4 hours.
