To prevent them, more states and cities are using infrared sensors and lasers that detect tall vehicles and warn drivers to turn around or take another route. “There have been bridges that have been brought down or severely damaged to the point they have to be replaced.” “Bridge strikes are potentially catastrophic,” said Darrin Roth, a vice president at the American Trucking Associations, a trade group. They damage valuable infrastructure, create epic traffic jams and can be hazardous for other drivers who may be pelted with fallen debris or forced to swerve into another car. So-called bridge strikes occur all over the country when trucks or their loads are too tall to pass under highway bridges and overpasses. “I’ve never seen damage that bad in 30 years,” said Ted Kniazewycz, director of the Tennessee Department of Transportation’s structures division.

Nobody was hurt, but the driver’s mistake snarled rush-hour traffic and forced workers to labor for more than 16 hours to remove the damaged beam and extricate the truck.

The driver of the tractor-trailer that was hauling the tanker had ventured more than a hundred miles from his approved route through Arkansas and west Tennessee. Just before saving these changes, the last screenshot below here shows the two segments of freeway selected to show that they too no longer have a junction where they previously intersected with the overpass.The Caterpillar tanker truck weighed 70,000 pounds, and when it struck an overpass above Interstate 65 in downtown Nashville in April 2018, it twisted one of the steel support beams as if it were a pipe cleaner. You can leave these nodes in place or delete them depending on the situation and whether they are necessary to keep the segment aligned with aerials or GPS points. This is normal, and is exactly like what happens when you delete an unnecessary junction node in the middle of a segment. Notice that there are two geometry nodes where there used to be junctions. When all the segments are bridged and joined together, you will have something similar to what is shown in the next screenshot. The two segments to select now are the "new" segment created from the first step, and the next segment to the right. Different situations may require only one join, and some may require more than two. In order to complete the overpass in this example, we need to repeat the process one more time. There is now a new segment which was created by joining the two segments in the last step.

The other two intersecting segments (in this case of the freeway), are also joined together into a single segment.

The Elevation of the new segment is set to 1 level higher than the higher Elevation of the two segments which were joined.

The two selected segments are joined into a single segment.

If segment properties match as described above, a small black bridge icon will appear above where the two segments meet, as shown below.Ĭlick the bridge icon and three things happen: The first step is to select two adjacent segments of what is to become the bridge or overpass. Road type, directionality, locked and separating line settings do not matter. The attributes which need to match are country, state (applicable countries only), city, and street name. Before you will be allowed to bridge, several properties of the segments to be bridged must be identical. This same is true of both sides of this interstate.īridging works on only two segments at a time. First, in this view, you can see that there is a junction between the interstate freeway and an overpass.
