(WBBM NEWSRADIO) -- The state has opened an investigation into the elimination of a bus program for senior citizens and people with disabilities in a northwest suburban township.The McHenry Township Board voted in June to eliminate the bus service, but the board was scheduled to reconsider that decision on Thursday.The board also was expected to certify a referendum for the next election to ask voters whether they think the bus service should continue.Township Supervisor Craig Adams said the Senior Express Bus Service provides about 14,000 rides a year and is valuable because "we are door to door" and get people to doctor visits, grocery stores and recreation centers. While Pace buses will pull up to a curb to provide a ride to a senior or someone who is disabled, the township's service goes up to the driveway and the driver helps the rider get into the vehicle, he said.Adams said the township leases five buses from Pace for $100 a month. The township is responsible for maintenance. He says the service gets about $50,000 in grants and about $200,000 a year from taxpayers to run the program.Adams acknowledges the Illinois Attorney General’s Office has begun investigating the board’s original action as a possible violation of the Americans with Disabilities Act.
