Excerpt from Comparative Design for a Highway Bridge: Thesis
The site is along Spring Creek about one and one - half miles outside of the city limits of Springfield, Illinois. This water way is a shallow stream, carrying a comparatively large quantity of water during the spring season only.
The concrete structure in place is of the girder type. The material is a gravel concrete of the following proportions, 1 part I cement, 2 parts sand, and 4 parts gravel. The substructure i and floor were placed in the late fall of 1910; but as cold weather! Overtook the work, it was suspended for the winter and the girders added in the following spring.

Paperback. Zustand: New. Print on Demand. This book compares a steel bridge to a reinforced concrete one, both designed for the same site. An existing reinforced concrete bridge is investigated and an appropriate steel alternative is designed. The durability, cost, and appearance of the two are then compared. Steel bridges typically have a shorter life (25 years vs. 75 years for concrete) and require more maintenance, but are cheaper to build initially. However, when maintenance costs are factored into the lifetime value, the concrete bridge is a more cost-effective option. While the steel bridge is more aesthetically pleasing, the concrete bridge is still visually appealing and less prone to problems resulting from poor construction. The author concludes that concrete bridges are a better choice for this type of highway span, especially when durability and cost are key considerations.
