The street runs in a straight line from Custom House Street to Grand Parade. Other streets lead off from Oliver Plunkett Street in a grid pattern, such as Prince's Street, Cook Street, and Smith Street. With 15 streets on both sides of Oliver Plunkett Street, there are a number of access points to the street from
St. Patrick's Street to the north and the South Mall to the south. Between Grand Parade and
Parnell Place, the street is a shopping street. This section of the street is also home to Cork's
General Post Office. A small lane, known as Market Lane, provides access to the
English Market. There are over one hundred independent retailers on the street, many of which have been family-owned for several generations. It is also one of a number of nightlife centres in Cork - although there are more bars and restaurants on the neighbouring side streets than on Oliver Plunkett Street itself. Between Parnell Place and Custom House Quay, the east end of the street is known as
Oliver Plunkett Street Lower. ==Pedestrianisation==
