The project E18 Varodd bridge is situated on the E18 just east of the centre of Kristiansand and it crosses Topdalsfjorden. The new bridge (Varodd bridge south) shall be constructed as a cantilever bridge (FFB) and it shall be constructed between the two existing bridges, which are a suspension bridge from 1956 (Varodd bridge (1956)) and a cantilever bridge from 1994 (Varodd bridge (1994)). A new foot and cycle path system shall also be constructed and Varodd bridge (1956) shall be demolished. The new Varodd bridge south must first be built with a reduced cross section on part of the length, and then completed after that Varodd bridge (1956) has been demolished.
The E18 must maintain its dual carriageway throughout the construction site area for the entire construction period. A foot and cycle path system shall also be maintained throughout the entire construction period.
The current E18 has an annual daily traffic count of approx. 50 000.
This is a model based assignment in accordance with the Norwegian Public Roads Administration's hand book R760.
Brief description of the assignment:
— Alteration, new construction of the E18 eastbound and westbound lanes with the adjoining local roads/ramps, including signs, water and sewage and electro.
— Footpath systems locally at Søm and Varodd, including signs, water and sewage and electro.
— Terrain measures for the construction of roads and bridges, including dry walls of natural stone.
— Construction of Varodd bridge south.
— Construction of 3 foot/cycle path bridges: Varodden, Sømslandet down and Sømslandet up.
— Alterations to a culvert in Narviga: Varen.
— Alterations to covers, railings, signs and lighting on Varodd bridge (1994).
— Demolition of Varodd bridge (1956), culvert at Søm and steps to Vardåsen.
— Alterations of municipal water and sewage installations at Søm.
— Construction of noise reduction screen.
Project E18 Varodd Bridge is located on the E18 just east of central Kristiansand,
crosses over Topdalsfjorden. New bridge (Varodd Bridge south) shall be performed as a stand-up construction bridge (FFB), and will be built between the two existing bridges, which is a suspension bridge 1956 (Varodd Bridge (1956)) and a free-construction bridge from 1994 (Varodd Bridge (1994) ). It will also be built a new pedestrian and cycle system, and Varodd Bridge (1956) will be demolished. The new Varodd Bridge south must first be built with reduced cross-section of a portion of the length, then completed after Varodd Bridge (1956) is torn.
There is no requirement to maintain 4 lane on the E18 through the construction site throughout
construction period. It should also be maintained footpaths cycle system throughout the construction period.
Today's E18 has an ADT of about 50000.
This is a model-based assignments according to NPRA Manual R760.
Brief summary of the mission:
• Rebuilding, construction of E18 eastbound and westbound run with adjoining
local roads / ramps incl. sign, VA and electro.
• Footpath systems locally on Sewing & TA incl. Sign, VA and electro.
• Terrain Measures in connection with the construction of roads and bridges, including dry walls of
• Construction of Varodd Bridge south.
• Construction of 3 GS bridges: TA, Sømslandet down and Sømslandet up.
• Reconstruction of a culvert in Narviga: Item.
• Reconstruction of pavement, guardrails, signs and lighting on Varodd Bridge (1994).
• Demolition of Varodd Bridge (1956), culvert on Sewing and staircase to Vardåsen.
• Rebuilding of municipal sewage plant on Sewing
• Construction of noise barrier
The work consists mainly of the following works:
• Cracking of 58,000 m3 bedrock for filling
• 1100m road construction for the restructuring of road alignment.
• Filling of 48.000m3 in water by barge + nedsprengning of filling.
Cf. Chap. B2 section. 4.1.1 for qualification requirements.
Filling in water should not be performed in the period between April 1 and June 1 this occasion. regarding
County road moves 3m into Mannflåvannet on the new embankment, in order to establish
Fang trench is between road and mountain cutting. The county road is also added through soil extraction by Neset to improve curvature.
Dump Mannflåvannet shall have a minimum of 3 months to settle before dealing with roadway begins.
County road may be closed on HP 04 between kilograms metering 5.9 and 6.8 for 2 months in 2017. Closing period of 2 months to be coherent. Closures is a measure to ensure the safety blasting operations. Closing period shall not be for the period April 1 - June 1st. NPRA operating contractor Mandal contract prepares roadwork plan for detour roads during the period.
Fv 455 has a maximum limit of 10 tonnes axis weight. Vehicles with larger scale weight over 10 tons can be used only between 5.9 to 6.52 km in closing period in 2017.
Heaps be blasted within the plant by Mannflåvannet and quarries at Neset between kilograms metering 7.8 and 8.2.
