The two bridges are among the safest and best maintained infrastructures in Nova Scotia. Some of the safety measures include: wind detectors, mobile speed radar, bridge security, ice detection sensors, cameras and 12 emergency telephones on the Macdonald Bridge.
The speed limit on the Macdonald Bridge is 50km per hour and 70km per hour on the MacKay. The speed going through the toll lanes is 25km.
When a collision, even a minor one, takes place on one of the bridges, the impact is not minor. The vast majority of collisions are completely preventable and most often caused by driver distraction. The impact of even a minor collision on the bridges has a major impact on traffic congestion.
The HHB bridge patrol officers are special constables and with that have the authority to issue tickets for speeding, texting and other infractions.
