42Km

motorway

between Vaudreil-Dorion and Châteauguay

74 km motorway bypass south of the metropolitan area of Montreal, greatly reducing congestion in the city.

The contract includes the design, construction, financing, operation and maintenance of the 42 km motorway.

 

A30 is the largest transport project in the province of Quebec, and the second private public partnership (PPP). The project has provided a Bypass for the region that has allowed for a very significant reduction in congestion in the city centre and has provided an alternative route for heavy vehicle traffic.

 

The project consists of two long bridges, Beauharnois Bridge and Saint Lawrence Bridge, which are 1,860 and 2,552 metres in length, respectively. Due to the area in which they are located, both were built under harsh winter conditions. Despite this, they were successfully executed, with the established deadlines having been met.

The work can be divided into two sections: the western section, 42 km of new construction, where the aforementioned bridges are found, as well as 29 shorter bridges and one tunnel. And an added section approximately 32 km in length, which is part of the Operation, Maintenance and Rehabilitation concession contract.

The new construction section has the following characteristics:

  • 42 km of 4 lanes (2+2).
  • 2 long bridges, 1,860 and 2,552 metres respectively.
  • 29 structures (bridges and overpasses) and a tunnel.

General Information

  • Location:Montreal, Quevec, Canada

KEY ASPECTS

 
ACCIONA and our partners recognise the importance of the project in terms of regional economic development, employment opportunities and supply chain and training and skills development. Benefits for the region of this project include:

  • Creation of up to 18,900 full-time jobs during project construction and maintenance.
  • Increased economic activity in the region during the concession.
  • Reduced travel time across the range by up to 40 minutes for heavy commercial vehicles.
  • Higher cargo efficiency.
  • Improved road and driver safety.

SOCIAL INITIATIVES

This project generated around 18,900 direct and indirect jobs during and after the work execution period. In addition, thanks to its aim of circumventing the greater Montreal area, this motorway reduces the flow of vehicles through the island where Canada's second most populous city is located.

 

SUSTAINABILITY

The completion of the new A30 toll road greatly eases congestion in the greater Montreal metropolitan area, thereby reducing air pollution. During construction, special attention was paid to waste reduction by reusing much of the existing excavation material and using recycled materials in fillers, aggregates and concrete. The implementation of sustainable construction practices is beneficial from an economic and an environmental point of view, making it a practical and fundamental business decision for ACCIONA.

This project was built with maximum consideration given to the environmental impact study, which was carried out in accordance with provincial regulations. The specific guidelines described in the environmental impact study required that the project be designed and built following measures to minimise noise, dust and water pollution. Complying with these measures is essential to protect wildlife habitats, and ACCIONA works very closely with environmental and ecological consultants to ensure that impacts are kept to a minimum. To protect aquatic environments, we will use trestles or barges for river access and screens to capture sediment to avoid disturbing fish in spawning areas. When it is necessary to remove trees, we will avoid doing so in the spring to not disturb the nesting of local birds.

Beauharnois Bridge

The bridge crosses the shipping canal, the Beauharnois dam and the Saint Lawrence waterway. The bridge consists of two 14.22 m wide decks, one for each roadway and 3 m apart, with three lanes each. 43 sections: 2 pillars and 42 intermediate supports, between piles 28 and 29 (150 m section) composite structure. The elevation design is limited by the need to maintain a vertical gap of 38.5 m over the shipping channel. Two deck types were chosen to build the bridge, depending on whether the bridge crosses over land or water.

Saint Lawrence River Bridge

42 sections, 38 of which are 45 m long; the remaining four sections, two at each end, are 31 m in length. The bridge consists of two separate decks, each 12.57 m wide and with two roadways 3 m apart, supported by 82 pillars and four pillars. The base consists of shallow base foundations and micropiles; to prevent them from falling over, they are anchored to the rock with 7 m long micropiles.
