Important savings in cost of both labor and material are expected. System installed for prestressing piles at road's casting yard at North Little Rock, Ark., is described. Figures shown in recent AFE's prepared by MoPac engineering indicate that the cost per foot for a concrete pile trestle is only slightly higher than for a creosoted timber pile trestle. The advantages of the concrete trestle are that it gives (1) longer spans for passage of drift; (2) complete protection from fires with attendant savings in annual elimination of vegetation; (3) very low annual maintenance costs as compared to a timber trestle; and (4) a ballast-deck structure that gives continuity to the track structure.
