Improvements will make a temporary travel obstacle for some Sturgeon Bay drivers. Monday, June 7th marks the beginning of gas main construction at East Walnut Street. As early as 7:00 AM, East Walnut Street will be closed and open to local traffic, but only with access from South Lansing Avenue. South Neenah Avenue, however, will be open to thru traffic while work takes place. Construction is expected to be done by Tuesday evening, and drivers are asked to help ensure that by avoiding the area whenever possible. Staying away from barricades and closed roads has been a point of emphasis from the city, and doing so can help prevent a hard road closure.
