The main entrance to this underground station will be located on the northwest corner of Eglinton and Avenue Road; the second entrance will be located approximately 80 metres (260 ft) east on the north side of Eglinton. Retail spaces will be available at both entrances at street level. The station will have on-street connections to TTC buses and outdoor parking for 50 bicycles.[3] There is a third centre track on the east side of the station between the eastbound and westbound tracks either to store a train or to allow a train to change direction due to an emergency or a change in service.[4][5]
Avenue station was one of four underground stations that was "mined" (built using the sequential excavation method)[6] rather than being built using the cut-and-cover method like most of the other underground stations.[7][2] Both the station platform and the centre-track structure are part of a single circular tube, and there are no support columns between the three tracks. Shops were demolished to construct the two station entrances.[8][9]
In a report to the TTC Board on November 23, 2015, it was recommended that stations on Line 5 Eglinton should be given unique names.[10]Metrolinx initially proposed that the station be named "Avenue", for Avenue Road. Later, Metrolinx changed the proposed name to "Oriole Park". However, by January 2016, the proposed station name had been changed back to "Avenue" because "Oriole Park" was too similar to the name of another transit station within Toronto, namely Oriole GO Station on GO Transit's Richmond Hill line.[11]

One of three stations being built using what's known as the new Austrian tunneling method, or simply the "mining" method, Avenue Station reaches a depth of 32 metres (105 feet) underground at its northwest corner—the deepest point of any station in the system.

TTC staff evaluated the initial report and the proposed names and provided feedback and recommendations. A primary TTC concern was to avoid replication and redundancy with existing TTC station names. The proposed names are unique and are not likely to be confused with existing station names.
