To reach Tianjin Haihe High School, one can utilize a combination of public transportation options. The most convenient route typically involves taking the subway, specifically Line 2, which directly connects to the school. From the subway station, a short walk will lead to the school's entrance. Alternatively, one can also take a bus that stops near the school, although this may require a transfer and a longer walk. According to data from the Tianjin Public Transportation Bureau, the subway is the fastest and most efficient mode of transport, with an average travel time of approximately 20 minutes from the city center.

The preference for the subway is due to its direct route and high frequency of service. Line 2, which opened in 2012, has been instrumental in improving connectivity within the city and to key educational institutions like Tianjin Haihe High School. The data from the Tianjin Public Transportation Bureau indicates that Line 2 carries over 1.5 million passengers daily, making it one of the busiest subway lines in the city. This high ridership is a testament to the reliability and convenience of the subway system for students and staff of Tianjin Haihe High School. Additionally, the subway's integration with other public transportation modes, such as buses and taxis, provides flexibility for those who may need to transfer or require additional assistance.
