Traffic Cameras: Monitoring Stillwater Bridge 24/7?

The Stillwater Lift Bridge in Minnesota, which crosses the St. Croix River, has been a source of frustration for commuters and merchants due to the region's growing population and the bridge becoming a choke point. In 2017, the bridge closed to car traffic, with an expected shift in St. Croix Valley commuter traffic to the new St. Croix Crossing Bridge. The historic lift bridge is now used by pedestrians and cyclists and continues to allow boat traffic to pass through. The U.S. Geological Survey has installed cameras on the Stillwater Lift Bridge, providing nearly real-time views of the St. Croix River. This development allows for the monitoring of river conditions and the observation of water levels, temperature, and flow.

The Stillwater Lift Bridge has cameras

The Stillwater Lift Bridge, which crosses the St. Croix River between Stillwater, Minnesota, and Houlton, Wisconsin, is indeed equipped with cameras. In March 2024, the U.S. Geological Survey (USGS) installed a camera on the bridge, providing hourly images and time-lapse videos of the river and its surroundings. This camera is one of two operated by the USGS to monitor the St. Croix River, with the other located near Danbury, Wisconsin, almost 100 miles upstream.

The Stillwater Lift Bridge camera offers a unique perspective on the river, capturing the river's rise and the ice break-up during spring flooding. The time-lapse videos, compiled from images taken at hourly intervals, provide a fascinating visual record of the river's changing conditions. These videos and images are accessible to the public through the USGS's stream gage site, along with real-time data about water levels, temperature, and flow.

The installation of this camera is part of a relatively new initiative by the USGS to deploy cameras at their stream gages. According to the agency, these cameras allow them to confirm conditions rather than guess, enhancing their understanding and monitoring capabilities.

The Stillwater Lift Bridge itself is a historic structure that has undergone recent rehabilitation. Once used for car traffic, the bridge now serves as a bicycle and pedestrian crossing, providing a vital connection between Stillwater and the surrounding area. The bridge is staffed during specific seasons, with lift operators working to allow boats to pass through.

The bridge has played a significant role in the region's transportation network, though it has also been a source of frustration for commuters and merchants due to the traffic congestion it caused. Its closure to car traffic marked a notable shift, with the St. Croix Crossing bridge project opening to redirect commuter traffic and ease the strain on Stillwater's downtown area.

Traffic cameras on I-94 and I-694

Traffic cameras are an essential tool for monitoring road conditions and managing traffic flow. They provide real-time data and images that help authorities make informed decisions about road management and improve road safety. In this regard, the I-94 and I-694 highways are both equipped with an array of traffic cameras that serve these purposes.

The I-94 highway, stretching across multiple states, including Indiana, has numerous traffic cameras in place. In Indiana, the I-94 traffic cameras are located at various points, including Ambler, Beattys Corner, Brummitt Acres, Burns Harbor, Calumet Centre, Chesterton, Furnessville, Gary, and Hammond. These cameras provide live traffic updates, enabling authorities to monitor congestion, construction, and accidents along the I-94 corridor in Indiana.

Similarly, the I-694 highway, particularly in the Stillwater area, is also under constant surveillance by traffic cameras. These cameras are strategically positioned at various intersections and locations, including I-694 @ Stillwater Blvd, I-694 e/o McKnight Rd, and I-694 @ White Bear Ave. The cameras help capture real-time traffic conditions, allowing authorities to make timely decisions regarding traffic management and ensuring the safety of commuters.

In addition to the standard traffic cameras, the Stillwater Lift Bridge, which is part of the I-694 highway, has been equipped with a special camera by the U.S. Geological Survey. This camera provides nearly real-time views of the St. Croix River, capturing images upstream from the bridge. The images are updated hourly, and time-lapse videos can also be viewed, showcasing the river's changing conditions during spring flooding. This camera serves a unique purpose, providing valuable visual data on water levels, temperature, and flow, in addition to traffic monitoring.

The presence of these traffic cameras on I-94 and I-694 demonstrates the importance of real-time data in managing traffic flow and ensuring the safety of commuters. By utilising this technology, authorities can make informed decisions, improve traffic management, and enhance the overall driving experience for individuals travelling on these highways.

St. Croix River flooding

On June 12, 2024, the St. Croix River in Stillwater experienced flooding after heavy rainfall. Some areas near the river in Stillwater remained underwater, and Highway 48 was shut down due to the flooding.

The U.S. Geological Survey (USGS) installed a camera on the Stillwater Lift Bridge on March 21, 2024, which provides images of the river rising and the ice breaking up during spring flooding. The USGS's stream gage site also provides real-time data about water levels, temperature, and flow.

River conditions on the 255-mile St. Croix Riverway can vary significantly due to precipitation and location. The USGS and the U.S. Army Core of Engineers (USACE) provide resources to monitor river levels, including automated river level stations that display graphs of gauge height and discharge.

It is important for individuals to stay alert and plan accordingly when visiting rivers, especially during periods of high water levels.

Traffic congestion in Stillwater

Traffic congestion is a significant issue in many US cities, and Stillwater is no exception. With road closures, construction projects, and high traffic flow, Stillwater experiences its fair share of traffic woes.

Stillwater, Minnesota, and Stillwater, Oklahoma, have both been impacted by traffic congestion. In Stillwater, Minnesota, for example, the Stillwater Lift Bridge has been subject to closures and repair work, impacting traffic flow. The bridge, which spans the St. Croix River, is a critical transportation link in the area. Additionally, the city has seen lane closures on Interstate 35E/35W and Interstate 694, causing further traffic disruptions.

Stillwater, Oklahoma, on the other hand, has its own set of traffic challenges. The city's road network includes major roadways such as Boomer Road and Main Street. While specific incidents of traffic congestion in Stillwater, Oklahoma, were not readily available, the city is likely to experience traffic issues due to high traffic flow during peak hours and special events.

To manage traffic flow and improve road safety, both Stillwaters have implemented measures such as traffic cameras and traffic alerts. Stillwater, Minnesota, has several traffic cameras monitoring Interstate 94 and Interstate 694. These cameras provide real-time data on road conditions and traffic flow, helping commuters and transportation authorities make informed decisions. Similarly, Stillwater, Oklahoma, offers a traffic map that uses colour-coded lines to indicate traffic flow. Red lines represent heavy traffic flow, while green lines signify normal traffic or no traffic.

In recent years, traffic congestion in major US cities has been a pervasive issue. According to a report by INRIX, a transportation analytics company, drivers in major US cities lost an average of 51 hours to traffic in 2022. Chicago topped the list, with drivers losing an average of 155 hours to traffic congestion in 2022. While the COVID-19 pandemic led to a decrease in traffic levels, many cities are now experiencing a rebound in congestion, with some even surpassing pre-pandemic levels.

The bridge's closure to car traffic

The bridges closure to car traffic

Bridges are vital transportation links, but sometimes they need to be closed to car traffic due to construction, maintenance, or safety concerns. These closures can cause significant disruptions, so careful planning and management are necessary to minimise the impact on commuters and local communities.

In Stillwater, Minnesota, the historic Stillwater Lift Bridge has undergone a two-year rehabilitation project. During this time, the bridge has been closed to car traffic, with repair work being conducted. The bridge, which spans the St. Croix River, is being transformed into a bicycle and pedestrian crossing, offering a new mode of transportation for residents and visitors alike. To monitor the river, the U.S. Geological Survey has installed cameras on the Stillwater Lift Bridge, providing hourly images and time-lapse videos of the river's conditions.

In other instances, bridge closures may be due to construction projects. For example, the US 1 Bridge in Jupiter, Florida, is undergoing a replacement project, with the bridge closed to traffic for approximately 20 months. To mitigate the impact on the community, the Florida Department of Transportation has implemented a detour route and made intersection improvements to enhance traffic flow.

In Brisbane, Australia, the Victoria Bridge was permanently closed to general traffic in January 2021. To alleviate construction impacts, the local council has invested in a toll credit scheme for residents using the nearby Go Between Bridge. This demonstrates how bridge closures can be managed to minimise inconvenience and provide alternative options for commuters.

These examples highlight the various reasons for bridge closures and the strategies employed to manage traffic flow and ensure public safety during these transitions. By providing advanced notice, implementing detours, and offering alternative transportation solutions, communities can adapt to temporary or permanent bridge closures effectively.
