This action will get eliminate the narrowing that occurs after the start of the Malecon.
Also, new techniques are performed on the top step of the bus station in order to expand the highway without demolishing the bridge
The Government delegate, Rafael González Tovar, and the Head of the Demarcation of Roads, Ángel García Garay, visited the works of extension to third lane carriageway between Murcia and the Puerto de la Cadena found between mile markers 140 and 142, link up to the Malecon, and have a total length of just over 1 mile
González Tovar explained that last August 2009, the Government of Spain through the Ministry of Development launched the above work, which will expand to a third lane road Albacete sense of the A-30, in a section that supports a daily average of 140,000 vehicles.
In this regard, stressed that the government of Rodriguez Zapatero made an investment of 3,535,885 euros, with the goal of eliminating the funnel effect that occurs in the currently existing narrowing against the seawall (where locally lose one of the 3 lanes .)
Moreover, these works give continuity to that highway with 6 or more lanes between Puerto de la Cadena and the University will reach a length of 23 km and which will benefit traffic flow for drivers.
Also adding to the 3-lane joining from the Barrio del Carmen in the A-30 towards Albacete, generates a twisted lane that leads to the exit of Murcia-Center is a section of fourth lane to facilitate movement in and from the A-30, in a section that supports greater regional traffic.
It is noteworthy that these works have been planned and is carrying out the necessary measures to achieve the minimum condition, both the movement of vehicles and the residents of West Round Murcia.
New technique to avoid demolishing the bridge of the Bus Station
González Tovar explained that the State Highway Demarcation is making a new technique in the region to expand the bridge to the bus station with minimal disruption to traffic
To do this they are building a new steel piles, whose foundation will join the foundation of the existing batteries so that, after a charge transfer process, the bridge end resting on the new metal batteries, which are located outside the current.
These new batteries "embrace" under the current bridge, which will transfer your weight through tensioning rods housed in the holes made on the same spot where the bridge is based on the current battery, ensuring the same structural performance is today.
Once the charge transfer process, the old concrete piers are no longer necessary and can be demolished, thereby removing the obstacle that prevented the spread of the road, thanks to new steel piles to win wide enough to accommodate the new lane.
The government delegate in Murcia has expressed his satisfaction with the technical innovation is the solution adopted for the benefit of drivers and users of the bus station in Murcia.
The milestones of the work of widening the bridge are being:
Concrete connection between metal and foundation piles.
To ensure optimal transmission of the efforts of the board to the ground.
Simultaneously, work will supply steel bars to "sew" the existing board as new piles of metal.
Placement of steel rods sewn board - battery and installation of auxiliary equipment for the transfer of cargo.
Throughout this week will be placed above the steel bars at both ends of the structure, preparing the auxiliary hydraulic systems that once used to suspend the board and proceed with the charge transfer.
Charge transfer (transmission of the efforts of the board of the existing batteries with new batteries of metal).
Is planned, once the concrete connection between metal batteries and has acquired sufficient strength foundation.
Once the charge transfer from the first end of the board, teams will travel to the other end to perform the same operation.
Load test of structure, that operation will be executed before the commissioning of the bridge, to verify proper operation of the structure in accordance with the provisions in the draft, later moving to demolish the existing concrete piers.
On the second leg (pk 141 to 142 +000 +650), the extension is achieved using the median of the highway, thanks to the union of two independent boards that formed the viaduct of the Malecon.
To expand the platform of the A30 motorway, we calculated the new structure resulting from the union of two independent bridges that existed before the work, plus a new independent structure placed in the gap between them, supported on piles and foundation of new construction that does not overload the original structures.
Thus, the new structure is attached to the two bridges above only by the slabs of the new board compression, freeing the most of the function of each part of the structure and providing sufficient space for expansion of road.
The entire performance, which includes increased strongly in the stretch, you scheduled completion date of late October this year.
