The McHenry Avenue Project will widen McHenry Avenue to provide safety, operational, and capacity improvements to meet current and future traffic demands. The improvements will provide for the construction of a two-way center left-turn lane, widened shoulders to accommodate bicycles and pedestrians (Class III facility), a new traffic signal at the McHenry Avenue/River Road intersection, and the replacement of the two bridges (Stanislaus River and SSJID) with structures wide enough for the ultimate five-lane facility. Kjeldsen, Sinnock & Neudeck, Inc. (KSN) was retained by AECOM Transportation to provide surveying, mapping, and right of way engineering services for the 2-mile long improvement project. KSN’s services included establishing a survey control network, design support ground surveys, bathymetric surveys, bridge surveys, utility research and mapping, and right of way mapping. Right of way surveys included the preparation of a pre-construction record of survey to document the location of existing monuments and assisting the county with the preparation of descriptions for the acquisition of new right of way.
