The California Transportation Commission agreed to ensure that the southern connection from SR 125 to the new toll road would be funded in May 1996. Much of the routing for SR 125 south of SR 54 was determined in March 1997, and the Federal Highway Administration determined the "San Miguel Connector" routing that would connect the new freeway with SR 54 in August. The selection of the route, due to concerns over the destruction of the habitat of the Least Bell's Vireo, led to objections from county officials due to the proximity to homes and passing through the Bonita Golf Course and a Little League field. CTV spent $14 million on improving parks, and building Little League fields and trails to offset effects of the construction of the road. However, the construction of both SR 125 and Olympic Parkway were considered by Chula Vista officials to be essential for the further development for the eastern part of that city.
