Featured International Projects

Kobenhavn, Denmark

Storstrom Bridge (Storstrømsbroen),

This $295 million design-build (with a 5-year O&M agreement) multimodal bridge project will reduce congestion and improve the connection between Germany and Denmark. The project consists of a central Cable Stayed Bridge linking the islands of Masnedø and Falster in Denmark and it represents a fundamental step in the completion of the European North-South Corridor.

The cable stayed bridge prefabricated foundation, exceeding 13,000 tons, was transported to position underwater by equipment specifically designed for this project. This innovation provided a more efficient and standardize construction sequence, decreased safety risks, and eliminated delays caused by challenging weather conditions typical in this area.

Sao Paulo, Brazil

Eco Vias

The Eco Vias toll concession in Sao Paulo is part of IGLI concessions and operated under Ecorodovias. This DBFOM P3 concession carries 120,000 vehicles per day across six lanes and seven toll plazas.

Rio De Janeiro, Brazil

Eco Ponte

Eco Ponte is the largest toll bridge in the southern hemisphere, connecting Rio de Janeiro with the rest of the countryside. It services a population of 16.6 million people and carries 150,000 vehicles per day with two lanes in each direction and one toll plaza. Recycled materials were used to minimize future maintenance work and extend the life of the project.

Stockholm, Sweden

Arenastaden – Södra Hagalund Underground – SE

The section of the underground called “Arenastaden – Södra Hagalund” which connects southwards to the Green Line of the Stockholm underground network. The work, mainly underground in the municipality of Solna, consists of the construction of two stations (Arenastaden and Södra Hagalund), and a connecting tunnel about 2.5 km long.

Turin, Italy

A4 Turin to Milan

The A4 Turin to Milan concession connects three counties in Northern Italy; Turin, Novara, and Milan and serves 5.5 million people in the region. The project scope included widening to include a third lane and carriageway in each direction, revision of tolls, and adaptation of highway configuration to accommodate high speed railway lines parallel to the highway. Recycled materials were used to extend the life and reduce the need for frequent maintenance interruptions. This DBFOM concession carries 105,000 vehicles per day across three lanes, a carriageway, and an emergency lane in both directions.

Bardonecchia (TO), Italy

S.I.T.A.F. S.p.A.

Construction of Frejus safety tunnel

 

Solano County, CA

Cordelia Commercial Vehicle Enforcement Facility

SINELEC has been awarded a contract with the Solano Transportation Authority to install a state-of-the-art Commercial Vehicle Management System (CVMS) as part of their construction of a new commercial vehicle enforcement facility (CVEF). The facility is expected to process 1000 trucks an hour that will increase enforcement capacity, improve travel times, and improve safety by reducing back-ups on the highway. SINELEC is responsible for developing, implementing, and maintaining the CVMS system.

The system will measure, identify, and track vehicles that are overweight, over dimensional, out of regulatory compliance, have unsafe tires or overheating brakes. This will be completed by installing a series of state-of-the-art sensors overhead at strategic locations on the highway, along the ramps and at the inspection facility. This technology will allow the CVEF to process more than 3 times the number of vehicles per hour compared to current facilities.

Turin, Italy

A55 Turin Ring Road

This is a DBFOM P3 concession with approximately 430,000 vehicles per day with a three lanes-two carriageway- and emergency lane configuration. Recycled durable materials were used to minimize interruption from maintenance and optimize project life cycle.
