Tetra Tech INCA performed a site visit to evaluate engineering considerations including road and street crossings, structural elements such as walls and bridges. INCA prepared preliminary cost estimates for major items of work to develop a cost per mile construction cost.

INCA reviewed and commented on road and street crossings considering existing horizontal and vertical alignments which effect sight distance for crossing trail users as well as the motor vehicles. INCA engineers suggested changes regarding the application of traffic control devices to crossings of existing roads and streets.
