About the Medallion Design Competition

Thank you for playing a part in history!

After a steady stream of submissions, the Caldecott Fourth Bore Medallion Competition officially closed on Monday, May 7 at 4:30 p.m., as planned. The Caldecott Fourth Bore Project team is extremely grateful to participants in both communities for their interest in the project and participation in the competition.  We also acknowledge the many parents, teachers, and community representatives who supported these efforts.

The Caldecott Medallion Design Competition was launched on March 26 to provide children in grades K-12 in Alameda and Contra Costa Counties an opportunity to play a role in the design of an important architectural detail of the Fourth Bore.  The Competition drew more than 300 entries from both counties. Judging panels in each county will convene soon  to select designs for the medallions, which will be announced in June.

The Caldecott Tunnel Fourth Bore will have three "medallions" cast out of concrete on each side of the tunnel. The medallions will be located above the tunnel openings on the eastern and western sides and will become a part of this regional landmark for years to come.  The selected artwork will be used to design the molds which will create the Fourth Bore medallions, with three on each side of the tunnel. The original Caldecott Tunnel medallions that adorn the portals of the first two bores feature the decorative art deco style that was born in the 1920s. Art Deco is characterized by simple and bold geometric shapes, clean lines and often features abstract symbols.

“Art Deco Revisited” was selected as the Contest’s theme through an online public survey prior to the launch of the competition, in deference to the Art Deco medallions featured on the 1937 Caldecott tunnels. Students have exercised their creative imaginations around the theme "Art Deco Revisited" to explore ways that the past and present styles come together.
