Recently, a US media reported that a large petrochemical reactor was transported by truck to the ExxonMobil plant. The journey took more than a year and it was only transported for 30 miles (48.28032 km). 

According to ExxonMobil, the chemical reactor is part of an upgrade to the petrochemical facility in Rotterdam, the Netherlands. One of the three large reactor towers that are transported to the facility is about 100 feet high, 15 feet wide and weighs 700 tons, making it very cumbersome to transport. Once a large rig is installed, it takes 18 months for the fleet to transport the reactor. 30 miles.
