In a small bowl, whisk together the flour, baking soda and salt. Keeping the mixer on low-speed and slowly add the dry ingredients to the wet ingredients. Beat just until blended. Fold in the blueberries using a rubber spatula.
Using a fork, stir together the butter, flour, brown sugar and cinnamon in a small bowl until pea sized crumbs form. Set aside.
Pour the batter into a 9×5 inch metal loaf pan coated with cooking spray. Sprinkle the streusel mixture over the batter and bake at 350 degrees for 1 hour or until a toothpick inserted into the center comes out clean. Cool in pan for 10 minutes on a wire rack. Remove from pan and cool on rack.
In a separate small bowl, whisk together the sugar, milk and lemon juice until smooth. Drizzle the glaze over the banana bread.
Serve the banana bread warm or at room temperature.
