Coordinate with Design Division-Traffic Simulation and Safety Analysis Section for further guidance. Shows how it uses local under-utilized timber, achieves the same weight-bearing capability as a steel or concrete bridge, can be constructed with minimal equipment by public works crews, can be installed in a fraction of the time, and can reduce maintenance costs over time. Roadside safety performance is related to clear zone width and side slope rate. What is the highway type low volume two-lane, urban street, etc.
Where the clear zones given in this chapter are not met, safety treatment grates, extension, or guardrail will be required. What length and percentage of the project is affected by the design elements in question? Round and arched: 4:1, 6:1 and 10:1 Traversable Safety Bars Bars are made from 3-inch pipe. Easy attachment The safety slope end section can be attached using only standard wrenches.
Guardrails shall be upgraded to current hardware standards. Designers should carefully consider several factors before opting to use safety pipe runners. For parallel-drainage structures, a the roadway side slope or ditch slope should be 6:1 or flatter in the vicinity of the driveway, b the driveway slope should be 6:1 or flatter, c the transition between the side slope and the driveway slope should be rounded, and d safety treatment of the culvert opening should include an end section cut to match the driveway slope and have cross members grates spaced every 24 in.
Such circumstances would dictate that a more suitable, but lower priority, culvert end treatment be selected.

Where the cost of added length for new culverts or of extension of existing culverts is three or more times the cost of shielding with barrier, treatment with barrier becomes an attractive alternative.
