A bus bulb, also called a bus boarder or bus border, is an arrangement by which a sidewalk is extended outwards for a bus stop; typically the bus bulb replaces roadway that would otherwise be part of a parking lane. With bus bulbs or boarders, a bus can stay in its traffic lane to discharge and pick up passengers, instead of having to pull over to the curb.

The term bus bulb is prevalent in North American usage, whilst bus boarder or bus border is used elsewhere.

A bus bulb or boarder can be considered as a specific form of curb extension, although that term is more normally used to describe a sidewalk extension for the purposes of traffic calming or other traffic management purposes.

Benefits include preventing buses from being delayed by having to pull back into traffic, reducing risk of accidents, reducing pedestrian exposure in crosswalks (if provided at the same location), reducing sidewalk congestion, providing space for bus patron amenities including bus shelters, and traffic calming. The protrusion also facilitates easier full length alignment of a bus entrance with a raised kerb stop, especially to allow level boarding in the case of low-floor buses.

A bus ( /ˈbʌs/; plural "buses", /ˈbʌsɨz/, archaically also big car, omnibus, multibus, or autobus) is a road vehicle designed to carry passengers. Buses can have a capacity as high as 300 passengers. The most common type of bus is the single-decker rigid bus, with larger loads carried by double-decker buses and articulated buses, and smaller loads carried by midibuses and minibuses; coaches are used for longer distance services. Bus manufacturing is increasingly globalised, with the same design appearing around the world.

Buses may be used for scheduled bus transport, scheduled coach transport, school transport, private hire, tourism; promotional buses may be used for political campaigns and others are privately operated for a wide range of purposes.

Horse drawn buses were used from the 1820s, followed by steam buses in the 1830s, and electric trolleybuses in 1882. The first buses powered by internal combustion engines were used 1895^{[citation needed]} and this is still the most common power source. Recently there has been growing interest in hybrid electric buses, fuel cell buses, electric buses as well as ones powered by compressed natural gas or bio-diesel.

Andrew Jackson (March 15, 1767 – June 8, 1845) was the seventh President of the United States (1829–1837). Based in frontier Tennessee, Jackson was a politician and army general who defeated the Creek Indians at the Battle of Horseshoe Bend (1814), and the British at the Battle of New Orleans (1815). A polarizing figure who dominated the Second Party System in the 1820s and 1830s, as president he destroyed the national bank and relocated most Indian tribes from the Southeast to west of the Mississippi River. His enthusiastic followers created the modern Democratic Party. The 1830–1850 period later became known as the era of Jacksonian democracy.

Jackson was nicknamed "Old Hickory" because of his toughness and aggressive personality; he fought in duels, some fatal to his opponents. He was a rich slaveholder, who appealed to the common men of the United States, and fought politically against what he denounced as a closed, undemocratic aristocracy. He expanded the spoils system during his presidency to strengthen his political base.
