Drop-In Center, November 24, 2003

Listed below are the additional I-70 improvement alternatives that were developed after the September public meetings, and were on display at the November drop in center in Warrenton. Other than minor adjustments to minimize impacts to some properties, all other alternatives remain unchanged since the September public meetings. Please call 1-800-590-0066 if you have questions.

Montgomery County
Between Route 19 and High Hill - An additional alternative was developed to widen I-70 to the north of the existing location. Additional properties along the north side of I-70 would be impacted by this alternative.
Tree Farm Road (3.3 MB pdf)

Jonesburg Interchange - An additional alternative with changes along the north side of the interchange was developed to avoid impacts to a property potentially eligible for the National Register of Historic Places. Additional properties are affected by this alternative.

Warren County
Strack Church Road - The north outer roadway has been realigned to avoid impacts to properties potentially eligible for the National Register of Historic Places. Additional properties in this area would be affected.

Wright City (Exit 199) - The north outer roadway in Alternative 1 has been modified, but impacts no additional properties.
Wright City (Exit 200) - The south outer roadway has been eliminated. Outer roadway traffic will be rerouted onto Second Street.

St. Charles County
Lake St. Louis Blvd. Interchange - The diamond interchange alternative shown at the September public meetings was eliminated and replaced with single point urban diamond interchange to better handle anticipated traffic. Fewer properties would be impacted by this change.
Lake St. Louis Blvd. and Route 2 (2.4 MB pdf)

Wentzville Parkway and Route Z Interchanges - Previous alternatives for Wentzville Parkway have been eliminated since it has been found that this recently reconstructed interchange can handle future projected traffic volumes with only the addition of a second right turn lane on the westbound I-70 exit ramp. At Route Z, the ramps on the north side of the interchange were revised to avoid impacts to properties potentially eligible for the National Register of Historic Places. No new properties would be affected.

Public Meeting, September 23 & 25, 2003

The exhibits below display the variety of improvement alternatives that were considered for interchanges along I-70 in Montgomery and Warren Counties. The alternatives are shown at a small scale, and green check marks indicate those that have been retained for further study. Large scale versions of the retained alternatives are available farther down this page.

Following are maps of the retained alternatives. These are preliminary and subject to change based on further evaluation. In many places, two improvement alternatives are being considered. They are shown in no particular order or preference.

These are very large files that may be difficult to download with a slow computer connection. We suggest you use the most recent version of Adobe Acrobat Reader (6.0) to view the files. That program is available for free download at www.adobe.com. If you have trouble opening and viewing the files, contact the project office at 1-800-590-0066. The office is staffed from 9-5 on weekdays, and calls are returned within 24 hours.
