Design these spans in accordance with the AASHTO Standard LRFD Bridge Design Specifications. The main reinforcement should be set to provide 2 inches (65 mm) clear from top of slab and 1 inches (32 mm) clear from bottom of slab and the beam bolster spacing shall be 1'-6" (450 mm). Metal Stay-In-Place Forms
Bridge Division utilizes two types of prestressed concrete girders for the design of bridges: 1. AASHTO Shapes 2. Bulb-T Shapes Steel beams, welded plate girders and other special designs are used on an as needed basis. See the accompanying Prestressed Beam Reference Guide for beam reinforcing details, bearing pad details and a strand pattern guide. Beam Dimensions Standard beam dimensions for both AASHTO and Bulb-T beams are shown below.
The AASHTO LRFD Bridge Design Specifications  contain provisions for precast full depth deck slabs. Portions of those provisions will be covered in this example. This example will be for a full depth precast concrete deck slab placed on girders that run parallel to the span.
W-Beam to Thrie-Beam bridge transitions may need to use the non-symmetric W-to-Thrie connector that keeps the top height of the entire rail at approximately 31 inches. In addition, there is no need to transition in height to many 27 -inch high terminals.
Almost all existing W-beam guardrail systems that connect directly to a bridge rail without adequate blockouts or a rub rail near the bridge connection should be considered unsatisfactory because they can result in vehicle snagging, which in turn can contribute to a catastrophic accident.

exterior beam was used for all variations of the typical section. This is in the range of standard overhangs for closed box and I-beam bridges. Beam spacings of 6, 8, 10, and 12 ft were chosen to represent a reasonable upper and lower bound of spacings in use today.
Off-System 24-Ft Rdwy Bridge Standards Available for download Prestressed I-Girder standards are available for structures with Type Tx28 thru Tx62 girders. These are included in our issued set of Prestressed Concrete I-Girder standards.See MISCELLANEOUS STANDARDS section in the list for all additional standard drawings required.

the roadway approaches, the height of the bridge curb above the roadway shall be not less than 8 inches, and preferably not more than 10 inches. Where sidewalks are warranted for pedestrian traffic on urban ex pressways, they shaH be separated from the bridge roadway by the use of a traffic or combination railing as shown in Figure 1.1.9.
This chapter of the manual is broken into roadway classifications such as urban streets, suburban roadways, two-lane highways, multilane rural highways, and freeways. Chapter 4 describes non-freeway rehabilitation (3R) project design criteria.

For a highway bridge over a railroad, the governing regulation is 646.214(a)(2). The State transportation agency should follow its normal specifications, design standards, and guidelines for Federal-aid highway projects, depending whether it is on or off the National Highway System (NHS).
The standard single-span PPCB bridges have lengths varying from 46.33 to 110 feet and skews from 0 to 30 degrees. The standard three-span PPCB bridges have lengths varying from 126.33 to 243 feet and skews from 0 to 45 degrees. The standard rolled steel beam bridges, which are intended for stream crossings and county road overpasses, have lengths

bottom of the bridge deck in the primary direction. 2. Shear Effects. By using the strip method, an 8-in. deck is designed for flexure, and shear effects can be neglected. Figure . 404-1A illustrates the cross section of a typical beam-slab bridge with four beams spaced at 10 ft, a minimum-depth 8-in. concrete deck, and concrete railings.
Bridge Rehabilitation Railing Older decks may only be 6 1/2 thick. This makes it difficult to install the anchor system without drilling through the deck. On past projects, we have installed a bar at an angle to use the beam flange as a drill stop.
