During construction, West Spain Street will remain open to local traffic, but temporary lane closures and parking restrictions will be required. Access to homes and businesses will be maintained, though brief delays should be expected. 

What to expect: 

• Temporary traffic control and detours 
• Construction noise and equipment during daytime hours 
• On-street parking restrictions in work zones 
• Pedestrian detours around sidewalk repair areas 

The City and its contractor will make every effort to minimize disruptions and provide advance notice to nearby residents and businesses.
