I do not believe there is one from Altera.
I do think that the is one in the opencore community. Or perhaps on Nios Forum? - Altera_Forum

Altera does not support wishbone bridge for sure.

As far as I know, wishbone interconnect is similar to Altera's avalon interconnect.
Altera does provide 2 Avalon-MM bridges: pipeline bridge and clock crossing bridge. See which one is suitable to your need. - Altera_Forum

The Wishbone bus connects very easily to the Avalon bus. You just need to add a bit of combinatorial logic. See if this link helps:
http://en.wikipedia.org/wiki/wishbone_(computer_bus) There are several examples out there (The OpenCores MAC and I2C cores have been ported to Avalon). Jake - Altera_Forum

The attached file is a wrapper that I once wrote to connect the OpenCores MAC which has a wishbone slave and a wishbone master to the avalon bus.
