N/A = not applicable A culvert installation crew would support both the rail and portal road construction projects. The rail project requires about 150 culverts that would consume most of the culvert installation crew's time. It is estimated the culvert installation crew would be on site for six months, as shown in Table 2-6, Culvert Installation.

N/A = not applicable Track construction would be a labor and truck-delivery intensive operation. Over 4,000 semi-truck loads of material would be required to deliver all of the sub-ballast and track material to the site. The actual track-laying operation would involve stringing material (ties, tie plates, spikes, etc.) out for the length of the track. Most of the ties would likely be constructed of concrete. The rail would probably be delivered by rail in 1,400-foot, continuously welded sections; however, it is possible that it might be delivered by truck in 39-foot sections and welded in place. For Table 2-7, Track Material Delivery, it is assumed that ballast and rail would be delivered by rail. Ties and other track material would be delivered to Mack by rail and transloaded to trucks for delivery to the work site. The duration of this work is anticipated at six months, as shown in Table 2-8, Track Construction. 2-40
