Growing traffic volume along a stretch of the Boston Post Road, near two churches and an elementary school, has prompted a parking ban to be imposed by state and local officials.

The eastbound side of the road, also known as U.S. Route 1, near Noroton Avenue — an area directly in front of St. John’s Church — is now posted as “No Parking At Any Time.” This includes the area just east of the mid-block crosswalk near Hindley School and the Noroton Presbyterian Church.

The parking ban was imposed because “traffic volume has increased exponentially over the years to the point that traffic flow and safety in the area of the Noroton Avenue was compromised, resulting in numerous collisions and many more ‘near misses,’ ” police announced Tuesday.

The ban was imposed after consultations between the state Department of Transportation and the town’s Traffic Authority.

The parking restriction affects only the eastbound side of the Boston Post Road, officials said, and parking still is allowed on the westbound side in front of the commercial outlets there.

In the near future, the state Department of Transportation and the town will post more signs and street markings to clearly designate travel lanes and dedicated parking spaces in the area.
