Prevent a Freeway from Crossing and Destroying a Nature Preserve

In Orange County, located in Southern California, a very unique environment with very rare and endangered wildlife is being threatened by the constritcion of a new community, Rancho Mission Viejo. The community is undoubtedly going to be built, with 2 out of 5 communities already complete. The one aspect that can be prevented is a continuation of the 241 toll road to cross straight through St. Riley's wildlife preserve, which is approved but not set in stone. The extended toll road would almost touch Tesoro Highschool, the one thing permitted to be built in the nature reserve. The school, however, preaches environmental protection and takes care of the reserve (removing dry brush in summer to prevent fires, collecting information on animal life, removing invasive species, etc). The new road will pave over a natural stream a split the reseve in half and will kill a number of native deer,coyotes, snakes, frogs, and more. Please help to prevent the growing destruction of nature for convenience.
