The only rail crossing in La Broquerie will be closed for a day-and-a-half this week. CN Rail is taking the step so it can complete an upgrading project.  Spokesperson Jim Feeny understands it will be a huge inconvenience but adds the work must be done.  Detours will direct motorists to crossings one mile on either side of La Broquerie.  The crossing will be closed at 8 am Tuesday and be re-opened Wednesday at 6 pm.
