Cedar Viaduct

The Cedar Viaduct, the southern gateway into the Central Valley is now complete. Stretching over State Route 99 and taking future high-speed trains over the highway along with Cedar and North Avenues, the signature double span of arches can be seen from both sides of the highway. Construction on the Cedar Viaduct began in 2016. More than 8.6 million pounds of steel rebar and more than 37,000 cubic-yards of concrete were used to complete this signature structure. The Cedar Viaduct spans more than 3,700 feet long and more than 40 feet wide.

Over the summer, the arch cables between the double arches of the Cedar Viaduct were stressed. Shortly after, crews worked overnight to remove the falsework from underneath the structure that spans over State Route 99. Additional concrete will be placed to shape the parapet walls on top of the structure.

Concrete has cured and falsework has been stripped on all four of the concrete arches at the Cedar Viaduct in south Fresno. Arch cables have been installed between the arches and will be stressed in the coming weeks. The arch cables help support the load of the deck adding to the stability of the viaduct. Ironworkers have also tied rebar and will begin placing concrete for remaining portions of the parapet on top of the structure.

The arches at the Cedar Viaduct continue to take shape. To date, crews have placed more than 225 cubic-yards of concrete to form three of the four arches that span over State Route 99. Concrete to form the fourth and final arch will be placed later this spring. To the south of the Cedar Viaduct, embankment continues to be hauled and mechanically-stabilized earth (MSE) walls continue to go up bringing the Cedar Viaduct and structure at Muscat Avenue together.

Drive on State Route 99 through the City of Fresno and you can see the dual-span of arches beginning to take shape at the Cedar Viaduct. Crews can be seen building the falsework on both sides of the structure. Soon, ironworkers will begin to tie rebar for the arches. Each arch will be nearly 179 feet long and nearly 40 feet tall.

At the Cedar Viaduct in Fresno County, crews are installing the metal pan decking across the superstructure spanning over State Route 99. To the south, crews are working on tying rebar and removing forms for the parapet – or safety barrier – on top of the structure. When complete, the Cedar Viaduct will span nearly 3,700 feet long and will carry high-speed trains over State Route 99, North Avenue, Cedar Avenue, and Golden State Boulevard.

At the northern portion of the Cedar Viaduct, crews continue to construct the falsework for the structure taking high-speed trains over Golden State Boulevard. South of Golden State Boulevard, crews have begun stripping some of the falsework of the viaduct. Near State Route 99, carpenters continue to build the formwork for the arches and ironworkers continue to tie rebar for the arch beams.

In July, crews shut down State Route 99 (SR 99) overnight to place the last two precast girders to form the superstructure of the Cedar Viaduct. Ironworkers continue to tie rebar for the edge beams of the structure. When complete, the Cedar Viaduct will be nearly 3,700-feet long and will carry trains over SR 99, North and Cedar Avenues, and Golden State Boulevard.

At the Cedar Viaduct, crews have placed 38 of the 40 girders across the superstructure spanning State Route 99 (SR 99). North of SR 99, crews have begun formwork on an abutment for high-speed rail to cross over Golden State Boulevard. The Cedar Viaduct spans nearly 3,700 feet and crosses over SR 99, Golden State Boulevard, Cedar and North avenues.

This week, nighttime closures kicked off on State Route 99 as crews began the placement of precast concrete girders over the highway to connect the Cedar Viaduct. Near the south abutment of the structure, Martinez Steel has completed tying rebar, and crews are now placing concrete for the stems and soffit of the bridge deck. When complete, the Cedar Viaduct will be approximately three quarters of a mile long.

At the Cedar Viaduct on the south side of Fresno, crews continue constructing the pieces of the viaduct that will eventually cross over State Route 99. Ironworkers are currently tying rebar for an upcoming deck pour. Once the viaduct is complete on either side of the highway, precast concrete girders will be set to span the highway lanes. One of the largest structures on Construction Package 1, the Cedar Viaduct will be about three-quarters of a mile long when it’s complete.

At the Cedar Viaduct, crews are constructing another section of viaduct to cross over Cedar Avenue, as the structure gets closer to State Route 99. Once the viaduct has been built on either side of the highway, precast concrete girders will be set to span the highway lanes. One of the largest structures on Construction Package 1, the Cedar Viaduct will be about three-quarters of a mile long when it’s complete.

At the Cedar Viaduct, crews are constructing an abutment at the north end of the structure. Fill dirt will eventually be placed to transition trains to and from grade level and the viaduct. The Cedar Viaduct will be about three-quarters of a mile long when it’s complete.

At the Cedar Viaduct, construction crews continue extending the structure across State Route 99 south of Fresno. Columns for support piers are rising on both sides of the highway and in the median. Construction crews are now building the flared pier caps that will hold up the viaduct deck and extending the falsework from the already completed section. The viaduct will eventually be connected to the smaller Muscat Viaduct a little further to the south.
