Description

This station's main entrance is located at the southwest corner of the intersection with Don Mills Road. A secondary entrance is on the opposite northeast corner, with a new bus terminal stretching beyond that to Gervais Drive. The TTC bus terminal will have seven bus bays as well as on-street bus connections. An underground, accessible passage will link the bus terminal to the LRT concourse level, which will have retail spaces. The station will provide 30 outdoor and 30 indoor bicycle parking spaces. The underground Don Valley station was built using

method. The station is between two surface sections of the line. To travel under Don Mills Road, the line dips underground, passes through the station under the middle of Eglinton Avenue and re-emerges to the surface at the other side. To the west of Don Valley station, there is a facing-point crossover just beyond the ramp descending to the station's west portal. To the east of the station, there is a double crossover on the ramp descending to the station's east portal. As part of a program to install artworks at major interchange stations along Line 5 Eglinton, Don Valley station will feature an artwork titled ''Total Lunar Eclipse'' by British-American artist Sarah Morris. The artwork is a mural consisting of porcelain tiles that were silkscreened by hand. According to the artist, the artwork is a "wall painting" that "invites reflection on concepts of light, scale and motion through space". The station's main entrance has louvres in the glass panels above the doors. Metrolinx predicts that the louvres "will be a well-known and a distinctive part of the transit destination's look".

Name

During the planning stages for Line 5 Eglinton, the station was given the working name "Don Mills". On November 23, 2015, a report to the TTC Board recommended giving a unique name to each station in the subway system (including Line 5 Eglinton). Thus, the station was named "Science Centre" to reflect its proximity to the

(near the other terminus of the Ontario Line). When asked what this would mean for Science Centre station, Paul Calandra said the station would be renamed but did not speculate on what the new name might be. The following year, in 2024, the government announced that the Science Centre would close permanently following an engineering report that cited a significant risk of roof collapse. As a result of the closure, on March 28, 2025, Metrolinx announced that the unopened station would be renamed "Don Valley" to reflect the station’s proximity to the Don Valley Parkway and the Don River valley itself. Other names considered for the station were "Concorde", "Industrial District", "Olympia Square", "Ferrand", and "Don River".
