The American Association of State Highway and Transportation Officials (AASHTO) is a standards setting body which publishes specifications, test protocols, and guidelines that are used in highway design and construction throughout the United States. Despite its name, the association represents not only highways but air, rail, water, and public ...
Longer bridges can reduce the width of both shoulders to 4 feet (1.2 m). Existing bridges can remain part of the Interstate system if they have at least 12-foot-wide (3.7 m) lanes with 3.5-foot (1.1 m) shoulder on the left and a 10-foot (3.0 m) shoulder on the right, except that longer bridges can have 3.5 feet (1.1 m) shoulders on both sides.
To be included, the bridge should have a notable history of strikes. Many countries establish minimum standards for the structure gauge of bridges. For example, the United States requires a height of 14 feet (4.27 m) for highway bridges. [1] Some vehicle standards are made to conform to these expectations.
Highway designs in the US are subject to the AASHTO specifications, [4] [6] but the text does not contain specific procedures and recommendations. [2] Railway bridges are built according to the "Manual for Railway Engineering" [12] published by the American Railway Engineering and Maintenance-of-Way Association (AREMA).
The bridge inventory is developed for having a unified database for bridges, including the identification information; bridge types and specifications; operational conditions; and bridge data including geometric data, functional description, inspection data, etc. Bridge type and specifications classify the type of the bridge. That part provides ...
The primary US guidance is found in A Policy on Geometric Design of Highways and Streets published by the American Association of State Highway and Transportation Officials (AASHTO). [2] Other standards include the Australian Guide to Road Design Archived 2011-11-09 at the Wayback Machine, and the British Design Manual for Roads.
In addition, these toll facilities were grandfathered from Interstate Highway standards. A notable example is the western approach to the Benjamin Franklin Bridge in Philadelphia, where I-676 has a surface street section through a historic area. Policies on toll facilities and Interstate Highways have since changed.
