[5] Between Toa Alta and Corozal, the road can be dangerous during the night and rainy days because the area is very dark and the fog formation is frequent, causing poor visibility to drivers.

[10] Around the area where the river is located, the road is often covered by fog that forms at night and on rainy days, causing poor visibility and increasing the risk of traffic accidents.

[11][12] In 1990, the possibility of building a highway that would connect the town of Corozal with the San Juan metropolitan area was studied due to the population growth that the municipality experienced during those years and the limited employment opportunity available in the mountainous region of Puerto Rico.

[13] Consequently, construction of the highway began in 1996 as part of government efforts so that residents of Corozal and bordering towns in the interior of Puerto Rico would have direct access to the Autopista José de Diego (PR-22) and see reduced travel time to their workplaces in the metropolitan area.

In the short term, it is expected that the undivided road between Corozal and Dorado will be widened as a government initiative to reduce traffic accidents that have occurred on the highway.

If the proposed project is completed, the highway could facilitate people's access to their workplaces in the metropolitan area while potentially reducing travel time between both regions.
