We are on the downside of summer, but several Downtown street projects will continue to cause headaches for commuters well into fall and winter.

Major projects such as the Cultural Trail, Market Street ramp removal, addition of bicycle-only lanes and rebuilding of Illinois Street are mixing in with smaller but pesky projects involving sewer lines and sidewalks.

Overall, more than $58 million in construction work is under way, much of it federally funded in what are known as 80-20 projects, with the city coming up with 20 percent of the cost.

Here is a snapshot look at some of the Downtown projects that could cause traffic snags:

1 Project Open Market Just east of Downtown, the removal of the Market Street ramp to I-65 and touch-up work around a new interchange at Washington Street continue to cause some restrictions on Market, Washington, Pine and Division streets. This $22 million project should be completed by November.

2 Cultural Trail Various projects across Downtown are under way as part of this neighborhood-connecting project. The three-year job calls for a new urban path for bicycles and pedestrians connecting Fountain Square, Indiana Avenue, Mass Ave., The Canal area and Wholesale District. Project completion is November 2010.

3 Bike lanes A $209,000 project is squeezing in designated lanes for bicyclists along Michigan and New York streets, along with some new sidewalk ramps. These two bike corridors — set apart with painted lines — will extend from White River Parkway to Arlington Avenue.

4 Illinois Street project A $1.6 million resurfacing project from Washington Street to 16th Street is nearing the end. Completion is expected by November. Illinois is being resurfaced, bike lanes are being added, and some intersection work is being done.

Minor projects that also are causing traffic problems include:

5 South Alabama Street Restrictions due to utility work.

6 South Capitol Avenue Restrictions throughout this month due to Convention Center work, art project removal and inlet repairs.

7 North Delaware Street Restrictions through Nov. 4 to relocate water mains.

8 South Delaware Restrictions through Sept. 11 for steam main repair.

9 East Street Restrictions through Oct. 31 for basin replacement for United Water.

10 Monument Circle Restrictions for brick paving repair from Monument Circle, Meridian Street, Market Street and City Market.
