Two decades of protest led to the cancellation of all but the I-395 and I-695 portions of the plan, and the unbuilt portions of the project were finally cancelled in 1977. The failure to complete the Inner Loop left the Sousa Bridge's approaches incomplete and confusing. Unmarked Interstate 695 delivered three lanes of traffic to a one-lane on-ramp to the bridge, and traffic backed up for miles every day as a traffic light allowed only a few cars onto the bridge's southbound lanes during rush hour. An off-ramp delivered most northbound bridge traffic around the incomplete Barney Circle and under the bridge onto Interstate 695 westbound.
