An open house on regional transit options is set for today.

Jackson County Commuter Corridors Alternatives Analysis is holding three events this week to present information and take comments. Officials are studying which mix of rail and bus service would work best along Interstate 70 in Jackson County and along the old Rock Island line from Kansas City south through Raytown and Lee’s Summit.

The three events are:

• From 4 p.m. to 6 p.m. today at the Gamber Center, 4 S.E. Independence Ave., in Lee’s Summit. There will be short presentations at 4:15 and 5:15.

• 9 a.m. to 6 p.m. Wednesday at the Blue Springs South branch of the Mid-Continent Public Library, 2220 S. Missouri 7. Displays will be set up, and residents can leave their comments.

•  9 a.m. to 6 p.m. Thursday at the Southeast Community Center, 4201 E. 63rd St., Kansas City. Again, there will be displays and a chance for residents to leave their comments.

Part of the discussion is the proposed Kansas City Regional Rapid Rail system would have six spokes meeting at Union Station. The first two to be built would serve Eastern Jackson County, one on the Kansas City Southern line through Independence, Blue Springs and Grain Valley and one on the old Rock Island line. The other four would go to Liberty, Kansas City International Airport, the Legends development with Kansas Speedway and other attractions, and to Grandview.
