IDOT IL Route 171 & IL Route 7 Intersection Reconstruction
The Illinois Department of Transportation (I DOT) is currently engaged in preliminary engineering and environmental studies ("Phase I") for the intersection improvement of IL 7 (9th Street) at IL 171 (State Street). Currently, left turn lanes do not exist along IL 171 at the intersection of IL 7. This causes an unsafe condition for turning vehicles and contributes to overall congestion. The majority of the crash types experienced at this intersection are "Rear End" and "Turning", and in 2011, segments of IL 7 on both sides of IL 171 were listed in IDOT's FIVE PERCENT Report, which identifies highway locations with the most pressing safety needs.
PROPOSED IMPROVEMENTS CONSIST OF: • Traffic signal replacement
• Adding left turn lanes on IL 171
• Reconstructing on-street parking
• Providing new ADA compliant sidewalks and crossings within the project area
• Utility relocations and watermain replacement
(watermain replacement is 100% City cost)
• Filling the old coal vaults that currently reside under the
sidewalks as a safety measure for both pedestrians and building owners.
This intersection is located within Lockport's Downtown Historic District, which is listed on the National Register of Historic Places. In accordance with the established procedures for coordinating Illinois Department of Transportation projects, consultation with the Illinois State Historic Preservation Officer (SHPO) will continue through the Phase II (contract plan preparation) process. This project has received a "Conditional No Adverse Effect" finding that indicates the project meets the Secretary of the Interior's "Standards for Rehabilitation and Guidelines for Rehabilitating Historic Buildings" and that SHPO concurs with a finding of no adverse effect pursuant to 36 CFR 800, contingent upon the review and approval of Phase II plans when they are available.
NEXT STEPS AND FUNDING
After completion of Phase I, IDOT will initiate the preparation of contract plans ("Phase II"). No land acquisition is required for this project. The total construction cost is estimated to be $2.2 million and this project is a candidate for funding through the Highway Safety Improvement Program (HSIP) and is included in IDOT's Fiscal Year 2016-2021 Proposed Highway Improvement Program.
