Rosersberg road junction

Pro­ject and ob­jec­ti­ves

The Ro­sers­berg jun­c­tion will con­nect the Ro­sers­berg in­dust­ri­al park and the su­burb of Ro­sers­berg to the E4 mo­tor­way. This will im­pro­ve ac­cess both to the in­dust­ri­al area and the re­si­den­ti­al district. For the pe­op­le who li­ve in Ro­sers­berg, the new jun­c­tion me­ans that he­a­vy traf­fic will disap­pe­ar from the small ro­ads in their area, which will im­pro­ve ro­ad sa­fe­ty and re­du­ce no­i­se. The aim of the pro­ject is al­so to enab­le the Ro­sers­berg in­dust­ri­al park to be ex­ten­ded.

The cli­ent for the pro­ject is the Swe­dish Trans­port Ad­mi­nist­ra­tion, which is al­so re­s­pon­sib­le for co-fi­nan­cing the work, to­gether with the Sig­tu­na local autho­ri­ty and Ki­len­krys­set. The jun­c­tion is ex­pec­ted to be comp­le­ted in la­te 2012/ear­ly 2013.

De­scrip­tion

The task in­clu­des pro­du­cing a comp­le­te set of con­struc­tion docu­ments for the Ro­sers­berg jun­c­tion and its con­nec­tions.

Ge­o­sig­ma is re­s­pon­sib­le for the hydro­ge­o­lo­gi­cal aspects of the pro­ject. This is an im­por­tant con­si­de­ra­tion as the ground­wa­ter tab­le must be per­ma­nent­ly lo­we­red to enab­le the jun­c­tion to be built on the cho­sen si­te. In or­der to pre­vent fi­ne ma­te­ri­al in the lay­er of soil un­der the Ar­lan­da rail­way li­ne from be­ing washed out and to avo­id ground­wa­ter flows cau­sing da­mage to the ro­ad em­bank­ment, a cut-off wall will be built along­si­de the rail­way li­ne.
