Route 347 Design-Build, Phase 3

LKB was the lead designer of the NYS Route 347, Phase 3 from Terry Road to Gibbs pond Road in Smithtown. This fast-track, design build project will create a greenway corridor along a 1.1 mile section of roadway. The work consisted of widening of NY 347 to accommodate additional travel lanes, improvements to the horizontal and vertical alignment, pavement reconstruction, new drainage systems (including recharge basins and rain gardens), traffic signals at three intersections, solar powered street lighting, ITS, pavement markings, signs, new utilities (gas main, water mains, overhead electric), sound walls, a shared use path, sidewalks, a green stop, bus shelters and extensive landscaping.

The design and construction of this $36 million project was completed in 18 months. The work was constructed in three main stages of work with traffic maintained on the roadway throughout the project duration.
