Several plans have been announced for construction in 2011:

• Hank Aaron Trail extension. Presently the Hank Aaron State Trail ends at 94th Place in West Allis. Bikes can continue west on the old right of way but the pathway is quite rough, more suitable for mountain bikes than road bikes. Plans have been announced to put  in a temporary crushed stone surface connecting the HAST to the Oak Leaf Trail. Following the reconstruction of the Zoo Interchange, plans are to construct a paved surface.
• Lake Country Trail paving. Last year both the western and eastern ends of the Lake Country Trail were paved, leaving the middle section, mainly through Nagawaukee County Park, unpaved. On its website the Waukesha county parks department has announced that paving the middle section will start this spring. This announcement should be treated with a bit of skepticism since the paving of the middle section was originally announced for last year.
• Oak Leaf to Ozaukee Interurban Trail connector. For some time plans have developed, and grants have been announced, to build a trail connecting the Ozaukee Interurban Trail (in the person of the Brown Deer Trail at Brown Deer Road) to the Oak Leaf Trail at Hampton Avenue on the north edge of Estabrook Park. The connector would use both WE Energies right of way dating from the old Interurban tracks and unused railroad tracks. Phase I of this project from Brown Deer Road to Bradley Road, connecting the Brown Deer Trail to the Oak Leaf Trail at Brown Deer Park, scheduled to take place this summer. While short, this section would eliminate a very tricky left turn between Green Bay Road and the old village of Brown Deer, a turn that is dangerous in both directions.
• Downtown to Bay View connector. This path would utilize long-abandoned railroad tracks east of First Street between National Avenue and Kinnickinnic Ave, replacing part on the on-street route between downtown Milwaukee and Bay View. This project was first presented some years ago, unfortunately as an alternative to allowing bicycles on the Hoan Bridge.

I would be very disappointed if these are the only bike-oriented projects in southeastern Wisconsin. Please let me know about those I have missed.
