The closure will add to existing traffic problems in Gobowen, nearby Oswestry, while the railway station car park will also be closed.
Motorists will be unable to access the main village from the B5069 Oswestry during the work, from January 12-17.
A spokesman for Network Rail said: "Temporary, two-way traffic lights will be in place on January 18 and 19 and it is likely that Gobowen station car park will remain closed during this period subject to scheme progress.
"Rail services will be operating as normal during this time. Access will be maintained for pedestrians and cyclists to both the station and across the level crossing.
"We're sorry for any inconvenience this will cause."
