β° = Breakover angle; C = Underside of chassis; W = Wheel; G = Ground; M = Midpoint of wheelbase Example of a vehicle at a significant breakover angle.. Breakover angle or rampover angle is the maximum possible supplementary angle (usually expressed in degrees) that a vehicle, with at least one forward wheel and one rear wheel, can drive over without the apex of that angle touching any point ...
Approach (α) and departure angle (β) of a vehicle. Approach angle is the maximum angle of a ramp onto which a vehicle can climb from a horizontal plane without interference. [1] It is defined as the angle between the ground and the line drawn between the front tire and the lowest-hanging part of the vehicle at the front overhang.
A geometric design saved on construction costs and improved visibility with the intention to reduce the likelihood of traffic incidents. The geometric design of roads is the branch of highway engineering concerned with the positioning of the physical elements of the roadway according to standards and constraints. The basic objectives in ...

Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods.
The on and off ramps at the Commercial Street exit on northbound Interstate 5 will be closed through Sept. 23 as construction begins on a project to widen the freeway on Wednesday in Salem.
The first stage of the project, which includes the new toll plaza, widening, and the flyover ramps between I-95 and the turnpike, is projected to cost about $553 million. [3] The flyover ramps are expected to cost $142.9 million, with $100 million coming from federal funds and the remainder from the turnpike commission.
The first cloverleaf interchange patented in the US was by Arthur Hale, a civil engineer in Maryland, on February 29, 1916. [3] [4]A modified cloverleaf, with the adjacent ramps joined into a single two-way road, was planned in 1927 for the interchange between Lake Shore Drive and Irving Park Road in Chicago, Illinois, but a diamond interchange was built instead.
