NJ Route 29 Resurfacing and Drainage Improvements

Location: Hunterdon County, NJ

Client/Owner: NJDOT Division of Project Management

Phase: Concept Development 

Status: Concept Development Completed

This roadway resurfacing and drainage improvements project was an assignment under NJDOT General Engineering Services Agreement #2013PM921P0.  The assignment limits encompassed NJ Route 29 from milepost 19.80 to 34.30 in the City of Lambertville, Townships of Delaware and Kingwood, and Boroughs of Frenchtown and Stockton.

KMA conducted field investigation and hydrologic and hydraulic analyses of existing conditions at each of the twelve culverts and bridges along the project corridor.  Conditions for various alternatives to solve its persistent drainage problems were proposed, identifying where roadway swales would be re-graded, where extra inlets would be added, and where a new outfall would be placed.

The CD study entailed field survey, development of Final Design (FD) level base mapping, identification of existing conditions/roadway and structural deficiencies, development and evaluation of alternatives,a public involvement program, an environmental screening, and selection of a Preliminary Preferred Alternative (PPA).
